Apache Solr Release Notes
|
||
|
||
Introduction
|
||
------------
|
||
Apache Solr is an open source enterprise search server based on the Apache Lucene Java
|
||
search library, with XML/HTTP and JSON APIs, hit highlighting, faceted search,
|
||
caching, replication, and a web administration interface. It runs in a Java
|
||
servlet container such as Tomcat.
|
||
|
||
See http://lucene.apache.org/solr for more information.
|
||
|
||
|
||
Getting Started
|
||
---------------
|
||
You need a Java 1.6 VM or later installed.
|
||
In this release, there is an example Solr server including a bundled
|
||
servlet container in the directory named "example".
|
||
See the tutorial at http://lucene.apache.org/solr/tutorial.html
|
||
|
||
|
||
$Id$
|
||
|
||
================== 4.0.0-dev ==================
|
||
More information about this release, including any errata related to the
|
||
release notes, upgrade instructions, or other changes may be found online at:
|
||
https://wiki.apache.org/solr/Solr4.0
|
||
|
||
|
||
Versions of Major Components
|
||
---------------------
|
||
Apache Tika 1.1
|
||
Carrot2 3.5.0
|
||
Velocity 1.6.4 and Velocity Tools 2.0
|
||
Apache UIMA 2.3.1
|
||
Apache ZooKeeper 3.3.4
|
||
|
||
|
||
Upgrading from Solr 3.6-dev
|
||
----------------------
|
||
|
||
* The Lucene index format has changed and as a result, once you upgrade,
|
||
previous versions of Solr will no longer be able to read your indices.
|
||
In a master/slave configuration, all searchers/slaves should be upgraded
|
||
before the master. If the master were to be updated first, the older
|
||
searchers would not be able to read the new index format.
|
||
|
||
* Setting abortOnConfigurationError=false is no longer supported
|
||
(since it has never worked properly). Solr will now warn you if
|
||
you attempt to set this configuration option at all. (see SOLR-1846)
|
||
|
||
* The default logic for the 'mm' param of the 'dismax' QParser has
|
||
been changed. If no 'mm' param is specified (either in the query,
|
||
or as a default in solrconfig.xml) then the effective value of the
|
||
'q.op' param (either in the query or as a default in solrconfig.xml
|
||
or from the 'defaultOperator' option in schema.xml) is used to
|
||
influence the behavior. If q.op is effectively "AND" then mm=100%.
|
||
If q.op is effectively "OR" then mm=0%. Users who wish to force the
|
||
legacy behavior should set a default value for the 'mm' param in
|
||
their solrconfig.xml file.
|
||
|
||
* The VelocityResponseWriter is no longer built into the core. Its JAR and
|
||
dependencies now need to be added (via <lib> or solr/home lib inclusion),
|
||
and it needs to be registered in solrconfig.xml like this:
|
||
<queryResponseWriter name="velocity" class="solr.VelocityResponseWriter"/>
|
||
|
||
* The update request parameter to choose Update Request Processor Chain is
|
||
renamed from "update.processor" to "update.chain". The old parameter was
|
||
deprecated but still working since Solr3.2, but is now removed
|
||
entirely.
|
||
|
||
* The <indexDefaults> and <mainIndex> sections of solrconfig.xml are discontinued
|
||
and replaced with the <indexConfig> section. There are also better defaults.
|
||
When migrating, if you don't know what your old settings mean, simply delete
|
||
both <indexDefaults> and <mainIndex> sections. If you have customizations,
|
||
put them in <indexConfig> section - with same syntax as before.
|
||
|
||
* Two of the SolrServer subclasses in SolrJ were renamed/replaced.
|
||
CommonsHttpSolrServer is now HttpSolrServer, and
|
||
StreamingUpdateSolrServer is now ConcurrentUpdateSolrServer.
|
||
|
||
|
||

||
----------------------
|
||
|
||
New Features
|
||
----------------------
|
||
|
||
* SOLR-3272: Solr filter factory for MorfologikFilter (Polish lemmatisation).
|
||
(Rafał Kuć via Dawid Weiss, Steven Rowe, Uwe Schindler).
|
||
|
||
* SOLR-571: The autowarmCount for LRUCaches (LRUCache and FastLRUCache) now
|
||
supports "percentages" which get evaluated relative the current size of
|
||
the cache when warming happens.
|
||
(Tomas Fernandez Lobbe and hossman)
|
||
|
||
* SOLR-1932: New relevancy function queries: termfreq, tf, docfreq, idf
|
||
norm, maxdoc, numdocs. (yonik)
|
||
|
||
* SOLR-1665: Add debug component options for timings, results and query info only (gsingers, hossman, yonik)
|
||
|
||
* SOLR-2112: Solrj API now supports streaming results. (ryan)
|
||
|
||
* SOLR-792: Adding PivotFacetComponent for Hierarchical faceting
|
||
(erik, Jeremy Hinegardner, Thibaut Lassalle, ryan)
|
||
|
||
* LUCENE-2507, SOLR-2571, SOLR-2576: Added DirectSolrSpellChecker, which uses Lucene's
|
||
DirectSpellChecker to retrieve correction candidates directly from the term dictionary using
|
||
levenshtein automata. (James Dyer, rmuir)
|
||
|
||
* SOLR-1873, SOLR-2358: SolrCloud - added shared/central config and core/shard management via zookeeper,
|
||
built-in load balancing, and distributed indexing.
|
||
(Jamie Johnson, Sami Siren, Ted Dunning, yonik, Mark Miller)
|
||
Additional Work:
|
||
SOLR-2324: SolrCloud solr.xml parameters are not persisted by CoreContainer.
|
||
(Massimo Schiavon, Mark Miller)
|
||
SOLR-2287: Allow users to query by multiple, compatible collections with SolrCloud.

|
||
(Bruno Dumon, Sami Siren, Mark Miller)
|
||
SOLR-3080: Remove shard info from zookeeper when SolrCore is explicitlyunloaded.
|
||
(yonik, Mark Miller, siren)
|
||
|
||
* SOLR-1566: Transforming documents in the ResponseWriters. This will allow
|
||
for more complex results in responses and open the door for function queries
|
||
as results.
|
||
(ryan with patches from grant, noble, cmale, yonik, Jan Høydahl,
|
||
Arul Kalaipandian, Luca Cavanna, hossman)
|
||
SOLR-2037: Thanks to SOLR-1566, documents boosted by the QueryElevationComponent
|
||
can be marked as boosted. (gsingers, ryan, yonik)
|
||
|
||
* SOLR-2396: Add CollationField, which is much more efficient than
|
||
the Solr 3.x CollationKeyFilterFactory, and also supports
|
||
Locale-sensitive range queries. (rmuir)
|
||
|
||
* SOLR-2338: Add support for using <similarity/> in a schema's fieldType,
|
||
for customizing scoring on a per-field basis. (hossman, yonik, rmuir)
|
||
|
||
* SOLR-2335: New 'field("...")' function syntax for refering to complex
|
||
field names (containing whitespace or special characters) in functions.
|
||
|
||
* SOLR-2383: /browse improvements: generalize range and date facet display
|
||
(Jan Høydahl via yonik)
|
||
|
||
* SOLR-2272: Pseudo-join queries / filters. Examples:
|
||
To restrict to the set of parents with at least one blue-eyed child:
|
||
fq={!join from=parent to=name}eyes:blue
|
||
To restrict to the set of children with at least one blue-eyed parent:
|
||
fq={!join from=name to=parent}eyes:blue
|
||
(yonik)
|
||
|
||
* SOLR-1942: Added the ability to select postings format per fieldType in schema.xml
|
||
as well as support custom Codecs in solrconfig.xml.
|
||
(simonw via rmuir)
|
||
|
||
* SOLR-2136: Boolean type added to function queries, along with
|
||
new functions exists(), if(), and(), or(), xor(), not(), def(),
|
||
and true and false constants. (yonik)
|
||
|
||
* SOLR-2491: Add support for using spellcheck collation in conjunction
|
||
with grouping. Note that the number of hits returned for collations
|
||
is the number of ungrouped hits. (James Dyer via rmuir)
|
||
|
||
* SOLR-1298: Return FunctionQuery as pseudo field. The solr 'fl' param
|
||
now supports functions. For example: fl=id,sum(x,y) -- NOTE: only
|
||
functions with fast random access are reccomended. (yonik, ryan)
|
||
|
||
* SOLR-705: Optionally return shard info with each document in distributed
|
||
search. Use fl=id,[shard] to return the shard url. (ryan)
|
||
|
||
* SOLR-2417: Add explain info directly to return documents using
|
||
?fl=id,[explain] (ryan)
|
||
|
||
* SOLR-2533: Converted ValueSource.ValueSourceSortField over to new rewriteable Lucene
|
||
SortFields. ValueSourceSortField instances must be rewritten before they can be used.
|
||
This is done by SolrIndexSearcher when necessary. (Chris Male).
|
||
|
||
* SOLR-2193, SOLR-2565: You may now specify a 'soft' commit when committing. This will
|
||
use Lucene's NRT feature to avoid guaranteeing documents are on stable storage in exchange
|
||
for faster reopen times. There is also a new 'soft' autocommit tracker that can be
|
||
configured. (Mark Miller, Robert Muir)
|
||
|
||
* SOLR-2399: Updated Solr Admin interface. New look and feel with per core administration
|
||
and many new options. (Stefan Matheis via ryan)
|
||
|
||
* SOLR-1032: CSV handler now supports "literal.field_name=value" parameters.
|
||
(Simon Rosenthal, ehatcher)
|
||
|
||
* SOLR-2656: realtime-get, efficiently retrieves the latest stored fields for specified
|
||
documents, even if they are not yet searchable (i.e. without reopening a searcher)
|
||
(yonik)
|
||
|
||
* SOLR-2703: Added support for Lucene's "surround" query parser. (Simon Rosenthal, ehatcher)
|
||
|
||
* SOLR-2754: Added factories for several ranking algorithms:
|
||
BM25SimilarityFactory: Okapi BM25
|
||
DFRSimilarityFactory: Divergence from Randomness models
|
||
IBSimilarityFactory: Information-based models
|
||
LMDirichletSimilarity: LM with Dirichlet smoothing
|
||
LMJelinekMercerSimilarity: LM with Jelinek-Mercer smoothing
|
||
(David Mark Nemeskey, Robert Muir)
|
||
|
||
* SOLR-2134 Trie* fields should support sortMissingLast=true, and deprecate Sortable* Field Types
|
||
(Ryan McKinley, Mike McCandless, Uwe Schindler, Erick Erickson)
|
||
|
||
|
||
* SOLR-2438 added MultiTermAwareComponent to the various classes to allow automatic lowercasing
|
||
for multiterm queries (wildcards, regex, prefix, range, etc). You can now optionally specify a
|
||
"multiterm" analyzer in our schema.xml, but Solr should "do the right thing" if you don't
|
||
specify <fieldType="multiterm"> (Pete Sturge Erick Erickson, Mentoring from Seeley and Muir)
|
||
|
||
* SOLR-2481: Add support for commitWithin in DataImportHandler (Sami Siren via yonik)
|
||
|
||
* SOLR-2992: Add support for IndexWriter.prepareCommit() via prepareCommit=true
|
||
on update URLs. (yonik)
|
||
|
||
* SOLR-2906: Added LFU cache options to Solr. (Shawn Heisey via Erick Erickson)
|
||
|
||
* SOLR-3069: Ability to add openSearcher=false to not open a searcher when doing
|
||
a hard commit. commitWithin now only invokes a softCommit. (yonik)
|
||
|
||
* SOLR-1726: Added deep paging support to search (sort by score only) which should use less memory when paging deeply into results
|
||
by keeping the priority queue small. (Manojkumar Rangasamy Kannadasan, gsingers)
|
||
|
||
* SOLR-2802: New FieldMutatingUpdateProcessor and Factory to simplify the
|
||
development of UpdateProcessors that modify field values of documents as
|
||
they are indexed. Also includes several useful new implementations:
|
||
RemoveBlankFieldUpdateProcessorFactory
|
||
TrimFieldUpdateProcessorFactory
|
||
HTMLStripFieldUpdateProcessorFactory
|
||
RegexReplaceProcessorFactory
|
||
FieldLengthUpdateProcessorFactory
|
||
ConcatFieldUpdateProcessorFactory
|
||
FirstFieldValueUpdateProcessorFactory
|
||
LastFieldValueUpdateProcessorFactory
|
||
MinFieldValueUpdateProcessorFactory
|
||
MaxFieldValueUpdateProcessorFactory
|
||
(hossman, janhoy)
|
||
|
||
* SOLR-3120: Optional post filtering for spatial queries bbox and geofilt
|
||
for LatLonType. (yonik)
|
||
|
||
* SOLR-2459: Expose LogLevel selection with a RequestHandler rather then servlet
|
||
(Stefan Matheis, Upayavira, ryan)
|
||
|
||
* SOLR-3134: Include shard info in distributed response when shards.info=true
|
||
(Russell Black, ryan)
|
||
|
||
* SOLR-2898: Support grouped faceting. (Martijn van Groningen)
|
||
|
||
* SOLR-2949: QueryElevationComponent is now supported with distributed search.
|
||
(Mark Miller, yonik)
|
||
|
||
* SOLR-3221: Added the ability to directly configure aspects of the concurrency
|
||
and thread-pooling used within distributed search in solr. This allows for finer
|
||
grained controlled and can be tuned by end users to target their own specific
|
||
requirements. This builds on the work of the HttpCommComponent and uses the same configuration
|
||
block to configure the thread pool. The default configuration has
|
||
the same behaviour as solr 3.5, favouring throughput over latency. More
|
||
information can be found on the wiki (http://wiki.apache.org/solr/SolrConfigXml) (Greg Bowyer)
|
||
|
||
* SOLR-3278: Negative boost support to the Extended Dismax Query Parser Boost Query (bq).
|
||
(James Dyer)
|
||
|
||
* SOLR-3255: OpenExchangeRates.Org Exchange Rate Provider for CurrencyField (janhoy)
|
||
|
||
Optimizations
|
||
----------------------
|
||
|
||
* SOLR-1875: Per-segment field faceting for single valued string fields.
|
||
Enable with facet.method=fcs, control the number of threads used with
|
||
the "threads" local param on the facet.field param. This algorithm will
|
||
only be faster in the presence of rapid index changes. (yonik)
|
||
|
||
* SOLR-1904: When facet.enum.cache.minDf > 0 and the base doc set is a
|
||
SortedIntSet, convert to HashDocSet for better performance. (yonik)
|
||
|
||
* SOLR-2092: Speed up single-valued and multi-valued "fc" faceting. Typical
|
||
improvement is 5%, but can be much greater (up to 10x faster) when facet.offset
|
||
is very large (deep paging). (yonik)
|
||
|
||
* SOLR-2193, SOLR-2565: The default Solr update handler has been improved so
|
||
that it uses fewer locks, keeps the IndexWriter open rather than closing it
|
||
on each commit (ie commits no longer wait for background merges to complete),
|
||
works with SolrCore to provide faster 'soft' commits, and has an improved API
|
||
that requires less instanceof special casing. (Mark Miller, Robert Muir)
|
||
Additional Work:
|
||
SOLR-2697: commit and autocommit operations don't reset
|
||
DirectUpdateHandler2.numDocsPending stats attribute.
|
||
(Alexey Serba, Mark Miller)
|
||
|
||
* SOLR-2950: The QueryElevationComponent now avoids using the FieldCache and looking up
|
||
every document id (gsingers, yonik)
|
||
|
||
Bug Fixes
|
||
----------------------
|
||
|
||
* SOLR-3165: Cannot use DIH in Solrcloud + Zookeeper (Alexey Serba,
|
||
Mark Miller, siren)
|
||
|
||
* SOLR-3068: Occasional NPE in ThreadDumpHandler (siren)
|
||
|
||
* SOLR-2762: FSTLookup could return duplicate results or one results less
|
||
than requested. (David Smiley, Dawid Weiss)
|
||
|
||
* SOLR-2741: Bugs in facet range display in trunk (janhoy)
|
||
|
||
* SOLR-1908: Fixed SignatureUpdateProcessor to fail to initialize on
|
||
invalid config. Specifically: a signatureField that does not exist,
|
||
or overwriteDupes=true with a signatureField that is not indexed.
|
||
(hossman)
|
||
|
||
* SOLR-1824: IndexSchema will now fail to initialize if there is a
|
||
problem initializing one of the fields or field types. (hossman)
|
||
|
||
* SOLR-1928: TermsComponent didn't correctly break ties for non-text
|
||
fields sorted by count. (yonik)
|
||
|
||
* SOLR-2107: MoreLikeThisHandler doesn't work with alternate qparsers. (yonik)
|
||
|
||
* SOLR-2108: Fixed false positives when using wildcard queries on fields with reversed
|
||
wildcard support. For example, a query of *zemog* would match documents that contain
|
||
'gomez'. (Landon Kuhn via Robert Muir)
|
||
|
||
* SOLR-1962: SolrCore#initIndex should not use a mix of indexPath and newIndexPath (Mark Miller)
|
||
|
||
* SOLR-2275: fix DisMax 'mm' parsing to be tolerant of whitespace
|
||
(Erick Erickson via hossman)
|
||
|
||
* SOLR-2193, SOLR-2565, SOLR-2651: SolrCores now properly share IndexWriters across SolrCore reloads.
|
||
(Mark Miller, Robert Muir)
|
||
Additional Work:
|
||
SOLR-2705: On reload, IndexWriterProvider holds onto the initial SolrCore it was created with.
|
||
(Yury Kats, Mark Miller)
|
||
|
||
* SOLR-2682: Remove addException() in SimpleFacet. FacetComponent no longer catches and embeds
|
||
exceptions occurred during facet processing, it throws HTTP 400 or 500 exceptions instead. (koji)
|
||
|
||
* SOLR-2654: Directorys used by a SolrCore are now closed when they are no longer used.
|
||
(Mark Miller)
|
||
|
||
* SOLR-2854: Now load URL content stream data (via stream.url) when called for during request handling,
|
||
rather than loading URL content streams automatically regardless of use.
|
||
(David Smiley and Ryan McKinley via ehatcher)
|
||
|
||
* SOLR-2829: Fix problem with false-positives due to incorrect
|
||
equals methods. (Yonik Seeley, Hossman, Erick Erickson.
|
||
Marc Tinnemeyer caught the bug)
|
||
|
||
* SOLR-2848: Removed 'instanceof AbstractLuceneSpellChecker' hacks from distributed spellchecking code,
|
||
and added a merge() method to SolrSpellChecker instead. Previously if you extended SolrSpellChecker
|
||
your spellchecker would not work in distributed fashion. (James Dyer via rmuir)
|
||
|
||
* SOLR-2509: StringIndexOutOfBoundsException in the spellchecker collate when the term contains
|
||
a hyphen. (Thomas Gambier caught the bug, Steffen Godskesen did the patch, via Erick Erickson)
|
||
|
||
* SOLR-1730: Made it clearer when a core failed to load as well as better logging when the
|
||
QueryElevationComponent fails to properly initialize (gsingers)
|
||
|
||
* SOLR-1520: QueryElevationComponent now supports non-string ids (gsingers)
|
||
|
||
* SOLR-3037: When using binary format in solrj the codec screws up parameters
|
||
(Sami Siren, Jörg Maier via yonik)
|
||
|
||
* SOLR-3062: A join in the main query was not respecting any filters pushed
|
||
down to it via acceptDocs since LUCENE-1536. (Mike Hugo, yonik)
|
||
|
||
* SOLR-3214: If you use multiple fl entries rather than a comma separated list, all but the first
|
||
entry can be ignored if you are using distributed search. (Tomas Fernandez Lobbe via Mark Miller)
|
||
|
||
Other Changes
|
||
----------------------
|
||
|
||
* SOLR-1846: Eliminate support for the abortOnConfigurationError
|
||
option. It has never worked very well, and in recent versions of
|
||
Solr hasn't worked at all. (hossman)
|
||
|
||
* SOLR-1889: The default logic for the 'mm' param of DismaxQParser and
|
||
ExtendedDismaxQParser has been changed to be determined based on the
|
||
effective value of the 'q.op' param (hossman)
|
||
|
||
* SOLR-1946: Misc improvements to the SystemInfoHandler: /admin/system
|
||
(hossman)
|
||
|
||
* SOLR-2289: Tweak spatial coords for example docs so they are a bit
|
||
more spread out (Erick Erickson via hossman)
|
||
|
||
* SOLR-2288: Small tweaks to eliminate compiler warnings. primarily
|
||
using Generics where applicable in method/object declatations, and
|
||
adding @SuppressWarnings("unchecked") when appropriate (hossman)
|
||
|
||
* SOLR-2375: Suggester Lookup implementations now store trie data
|
||
and load it back on init. This means that large tries don't have to be
|
||
rebuilt on every commit or core reload. (ab)
|
||
|
||
* SOLR-2413: Support for returning multi-valued fields w/o <arr> tag
|
||
in the XMLResponseWriter was removed. XMLResponseWriter only
|
||
no longer work with values less then 2.2 (ryan)
|
||
|
||
* SOLR-2423: FieldType argument changed from String to Object
|
||
Conversion from SolrInputDocument > Object > Fieldable is now managed
|
||
by FieldType rather then DocumentBuilder. (ryan)
|
||
|
||
* SOLR-2461: QuerySenderListener and AbstractSolrEventListener are
|
||
now public (hossman)
|
||
|
||
* LUCENE-2995: Moved some spellchecker and suggest APIs to modules/suggest:
|
||
HighFrequencyDictionary, SortedIterator, TermFreqIterator, and the
|
||
suggester APIs and implementations. (rmuir)
|
||
|
||
* SOLR-2576: Remove deprecated SpellingResult.add(Token, int).
|
||
(James Dyer via rmuir)
|
||
|
||
* LUCENE-3232: Moved MutableValue classes to new 'common' module. (Chris Male)
|
||
|
||
* LUCENE-2883: FunctionQuery, DocValues (and its impls), ValueSource (and its
|
||
impls) and BoostedQuery have been consolidated into the queries module. They
|
||
can now be found at o.a.l.queries.function.
|
||
|
||
* SOLR-2027: FacetField.getValues() now returns an empty list if there are no
|
||
values, instead of null (Chris Male)
|
||
|
||
* SOLR-1825: SolrQuery.addFacetQuery now enables facets automatically, like
|
||
addFacetField (Chris Male)
|
||
|
||
* SOLR-2663: FieldTypePluginLoader has been refactored out of IndexSchema
|
||
and made public. (hossman)
|
||
|
||
* SOLR-2331,SOLR-2691: Refactor CoreContainer's SolrXML serialization code and improve testing
|
||
(Yury Kats, hossman, Mark Miller)
|
||

|
||
(Yury Kats, hossman, Mark Miller)

||
|
||
* SOLR-2654: The same Directory instance is now always used across a SolrCore so that
|
||
it's easier to add other DirectoryFactory's without static caching hacks.
|
||
(Mark Miller)
|
||
|
||
* LUCENE-3286: 'luke' ant target has been disabled due to incompatibilities with XML
|
||
queryparser location (Chris Male)
|
||
|
||
* SOLR-1897: The data dir from the core descriptor should override the data dir from
|
||
the solrconfig.xml rather than the other way round. (Mark Miller)
|
||
|
||
* SOLR-2756: Maven configuration: Excluded transitive stax:stax-api dependency
|
||
from org.codehaus.woodstox:wstx-asl dependency. (David Smiley via Steve Rowe)
|
||
|
||
* SOLR-2588: Moved VelocityResponseWriter back to contrib module in order to
|
||
remove it as a mandatory core dependency. (ehatcher)
|
||
|
||
* SOLR-2862: More explicit lexical resources location logged if Carrot2 clustering
|
||
extension is used. Fixed solr. impl. of IResource and IResourceLookup. (Dawid Weiss)
|
||
|
||
* SOLR-1123: Changed JSONResponseWriter to now use application/json as its Content-Type
|
||
by default. However the Content-Type can be overwritten and is set to text/plain in
|
||
the example configuration. (Uri Boness, Chris Male)
|
||
|
||
* SOLR-2607: Removed deprecated client/ruby directory, which included solr-ruby and flare.
|
||
(ehatcher)
|
||
|
||
* Solr-3032: logOnce from SolrException logOnce and all the supporting
|
||
structure is gone. abortOnConfugrationError is also gone as it is no longer referenced.
|
||
Errors should be caught and logged at the top-most level or logged and NOT propagated up the
|
||
chain. (Erick Erickson)
|
||
|
||
* SOLR-2105: Remove support for deprecated "update.processor" (since 3.2), in favor of
|
||
"update.chain" (janhoy)
|
||
|
||
* SOLR-3005: Default QueryResponseWriters are now initialized via init() with an empty
|
||
NamedList. (Gasol Wu, Chris Male)
|
||
|
||
* SOLR-2607: Removed obsolete client/ folder (ehatcher, Eric Pugh, janhoy)
|
||
|
||
* SOLR-3202, SOLR-3244: Dropping Support for JSP. New Admin UI is all client side
|
||
(ryan, Aliaksandr Zhuhrou, Uwe Schindler)
|
||
|
||
* SOLR-3159: Upgrade example and tests to run with Jetty 8 (ryan)
|
||
|
||
* SOLR-3254: Upgrade Solr to Tika 1.1 (janhoy)
|

|
||
|
||
* SOLR-3302: Upgraded SLF4j to version 1.6.4 (hossman)

|
||
from org.apache.solr.common to org.apache.solr.util (Chris Male)
|

|
||
Documentation
|
||
----------------------
|
||
|
||
* SOLR-2232: Improved README info on solr.solr.home in examples
|
||
(Eric Pugh and hossman)
|
||
|
||
================== 3.6.0 ==================
|
||
|
||
Upgrading from Solr 3.5
|
||
----------------------
|
||
* SOLR-2983: As a consequence of moving the code which sets a MergePolicy from SolrIndexWriter to SolrIndexConfig,
|
||
(custom) MergePolicies should now have an empty constructor; thus an IndexWriter should not be passed as constructor
|
||
parameter but instead set using the setIndexWriter() method.
|
||
|
||
* As doGet() methods in SimplePostTool was changed to static, the client applications of this
|
||
class need to be recompiled.
|
||
|
||
* In Solr version 3.5 and earlier, HTMLStripCharFilter had known bugs in the
|
||
character offsets it provided, triggering e.g. exceptions in highlighting.
|
||
HTMLStripCharFilter has been re-implemented, addressing this and other
|
||
issues. See the entry for LUCENE-3690 in the Bug Fixes section below for a
|
||
detailed list of changes. For people who depend on the behavior of
|
||
HTMLStripCharFilter in Solr version 3.5 and earlier: the old implementation
|
||
(bugs and all) is preserved as LegacyHTMLStripCharFilter.
|
||
|
||
* As of Solr 3.6, the <indexDefaults> and <mainIndex> sections of solrconfig.xml are deprecated
|
||
and replaced with a new <indexConfig> section. Read more in SOLR-1052 below.
|
||
|
||
* SOLR-3040: The DIH's admin UI (dataimport.jsp) now requires DIH request handlers to start with
|
||
a '/'. (dsmiley)
|
||
|
||
* SOLR-3161: <requestDispatcher handleSelect="false"> is now the default. An existing config will
|
||
probably work as-is because handleSelect was explicitly enabled in default configs. HandleSelect
|
||
makes /select work as well as enables the 'qt' parameter. Instead, consider explicitly
|
||
configuring /select as is done in the example solrconfig.xml, and register your other search
|
||
handlers with a leading '/' which is a recommended practice. (David Smiley, Erik Hatcher)
|
||
|
||
* SOLR-3161: Don't use the 'qt' parameter with a leading '/'. It probably won't work in 4.0
|
||
and it's now limited in 3.6 to SearchHandler subclasses that aren't lazy-loaded.
|
||
|
||
* Bugs found and fixed in the SignatureUpdateProcessor that previously caused
|
||
some documents to produce the same signature even when the configured fields
|
||
contained distinct (non-String) values. Users of SignatureUpdateProcessor
|
||
are strongly advised that they should re-index as document signatures may
|
||
have now changed. (see SOLR-3200 & SOLR-3226 for details)
|
||
|
||
|
||
New Features
|
||
----------------------
|
||
* SOLR-2020: Add Java client that uses Apache Http Components http client (4.x).
|
||
(Chantal Ackermann, Ryan McKinley, Yonik Seeley, siren)
|
||
|
||
* SOLR-2854: Now load URL content stream data (via stream.url) when called for during request handling,
|
||
rather than loading URL content streams automatically regardless of use.
|
||
(David Smiley and Ryan McKinley via ehatcher)
|
||
|
||
* SOLR-2904: BinaryUpdateRequestHandler should be able to accept multiple update requests from
|
||
a stream (shalin)
|
||
|
||
* SOLR-1565: StreamingUpdateSolrServer supports RequestWriter API and therefore, javabin update
|
||
format (shalin)
|
||
|
||
* SOLR-2438 added MultiTermAwareComponent to the various classes to allow automatic lowercasing
|
||
for multiterm queries (wildcards, regex, prefix, range, etc). You can now optionally specify a
|
||
"multiterm" analyzer in our schema.xml, but Solr should "do the right thing" if you don't
|
||
specify <fieldType="multiterm"> (Pete Sturge Erick Erickson, Mentoring from Seeley and Muir)
|
||
|
||
* SOLR-2919: Added support for localized range queries when the analysis chain uses
|
||
CollationKeyFilter or ICUCollationKeyFilter. (Michael Sokolov, rmuir)
|
||
|
||
* SOLR-2982: Added BeiderMorseFilterFactory for Beider-Morse (BMPM) phonetic encoder. Upgrades
|
||
commons-codec to version 1.6 (Brooke Schreier Ganz, rmuir)
|
||
|
||
* SOLR-1843: A new "rootName" attribute is now available when
|
||
configuring <jmx/> in solrconfig.xml. If this attribute is set,
|
||
Solr will use it as the root name for all MBeans Solr exposes via
|
||
JMX. The default root name is "solr" followed by the core name.
|
||
(Constantijn Visinescu, hossman)
|
||
|
||
* SOLR-2906: Added LFU cache options to Solr. (Shawn Heisey via Erick Erickson)
|
||
|
||
* SOLR-3036: Ability to specify overwrite=false on the URL for XML updates.
|
||
(Sami Siren via yonik)
|
||
|
||
* SOLR-2603: Add the encoding function for alternate fields in highlighting.
|
||
(Massimo Schiavon, koji)
|
||
|
||
* SOLR-1729: Evaluation of NOW for date math is done only once per request for
|
||
consistency, and is also propagated to shards in distributed search.
|
||
Adding a parameter NOW=<time_in_ms> to the request will override the
|
||
current time. (Peter Sturge, yonik, Simon Willnauer)
|
||
|
||
* SOLR-1709: Distributed support for Date and Numeric Range Faceting
|
||
(Peter Sturge, David Smiley, hossman, Simon Willnauer)
|
||
|
||
* SOLR-3054, LUCENE-3671: Add TypeTokenFilterFactory that creates TypeTokenFilter
|
||
that filters tokens based on their TypeAttribute. (Tommaso Teofili via
|
||
Uwe Schindler)
|
||
|
||
* LUCENE-3305, SOLR-3056: Added Kuromoji morphological analyzer for Japanese.
|
||
See the 'text_ja' fieldtype in the example to get started.
|
||
(Christian Moen, Masaru Hasegawa via Robert Muir)
|
||
|
||
* SOLR-1860: StopFilterFactory, CommonGramsFilterFactory, and
|
||
CommonGramsQueryFilterFactory can optionally read stopwords in Snowball
|
||
format (specify format="snowball"). (Robert Muir)
|
||
|
||
* SOLR-3105: ElisionFilterFactory optionally allows the parameter
|
||
ignoreCase (default=false). (Robert Muir)
|
||
|
||
* LUCENE-3714: Add WFSTLookupFactory, a suggester that uses a weighted FST
|
||
for more fine-grained suggestions. (Mike McCandless, Dawid Weiss, Robert Muir)
|
||
|
||
* SOLR-3143: Add SuggestQueryConverter, a QueryConverter intended for
|
||
auto-suggesters. (Robert Muir)
|
||
|
||
* SOLR-3033: ReplicationHandler's backup command now supports a 'maxNumberOfBackups'
|
||
init param that can be used to delete all but the most recent N backups. (Torsten Krah, James Dyer)
|
||
|
||
* SOLR-2202: Currency FieldType, whith support for currencies and exchange rates
|
||
(Greg Fodor & Andrew Morrison via janhoy, rmuir, Uwe Schindler)
|
||
|
||
* SOLR-3026: eDismax: Locking down which fields can be explicitly queried (user fields aka uf)
|
||
(janhoy, hossmann, Tomás Fernández Löbbe)
|
||
|
||
* SOLR-2826: URLClassify Update Processor (janhoy)
|
||
|
||
* SOLR-2764: Create a NorwegianLightStemmer and NorwegianMinimalStemmer (janhoy)
|
||
|
||
* SOLR-3221: Added the ability to directly configure aspects of the concurrency
|
||
and thread-pooling used within distributed search in solr. This allows for finer
|
||
grained controlled and can be tuned by end users to target their own specific
|
||
requirements. This builds on the work of the HttpCommComponent and uses the same configuration
|
||
block to configure the thread pool. The default configuration has
|
||
the same behaviour as solr 3.5, favouring throughput over latency. More
|
||
information can be found on the wiki (http://wiki.apache.org/solr/SolrConfigXml) (Greg Bowyer)
|
||
|
||
* SOLR-2001: The query component will substitute an empty query that matches
|
||
no documents if the query parser returns null. This also prevents an
|
||
exception from being thrown by the default parser if "q" is missing. (yonik)
|
||
SOLR-435: if q is "" then it's also acceptable. (dsmiley, hoss)
|
||
|
||
Optimizations
|
||
----------------------
|
||
* SOLR-1931: Speedup for LukeRequestHandler and admin/schema browser. New parameter
|
||
reportDocCount defaults to 'false'. Old behavior still possible by specifying this as 'true'
|
||
(Erick Erickson)
|
||
|
||
* SOLR-3012: Move System.getProperty("type") in postData() to main() and add type argument so that
|
||
the client applications of SimplePostTool can set content type via method argument. (koji)
|
||
|
||
* SOLR-2888: FSTSuggester refactoring: internal storage is now UTF-8,
|
||
external sorting (on disk) prevents OOMs even with large data sets
|
||
(the bottleneck is now FST construction), code cleanups and API cleanups.
|
||
(Dawid Weiss, Robert Muir)
|
||
|
||
Bug Fixes
|
||
----------------------
|
||
* SOLR-3187 SystemInfoHandler leaks filehandles (siren)
|
||
|
||
* LUCENE-3820: Fixed invalid position indexes by reimplementing PatternReplaceCharFilter.
|
||
This change also drops real support for boundary characters -- all input is prebuffered
|
||
for pattern matching. (Dawid Weiss)
|
||
|
||
* SOLR-3068: Fixed NPE in ThreadDumpHandler (siren)
|
||
|
||
* SOLR-2912: Fixed File descriptor leak in ShowFileRequestHandler (Michael Ryan, shalin)
|
||
|
||
* SOLR-2819: Improved speed of parsing hex entities in HTMLStripCharFilter
|
||
(Bernhard Berger, hossman)
|
||
|
||
* SOLR-2509: StringIndexOutOfBoundsException in the spellchecker collate when the term contains
|
||
a hyphen. (Thomas Gambier caught the bug, Steffen Godskesen did the patch, via Erick Erickson)
|
||
|
||
* SOLR-2955: Fixed IllegalStateException when querying with group.sort=score desc in sharded
|
||
environment. (Steffen Elberg Godskesen, Martijn van Groningen)
|
||
|
||
* SOLR-2956: Fixed inconsistencies in the flags (and flag key) reported by
|
||
the LukeRequestHandler (hossman)
|
||
|
||
* SOLR-1730: Made it clearer when a core failed to load as well as better logging when the
|
||
QueryElevationComponent fails to properly initialize (gsingers)
|
||
|
||
* SOLR-1520: QueryElevationComponent now supports non-string ids (gsingers)
|
||
|
||
* SOLR-3024: Fixed JSONTestUtil.matchObj, in previous releases it was not
|
||
respecting the 'delta' arg (David Smiley via hossman)
|
||
|
||
* SOLR-2542: Fixed DIH Context variables which were broken for all scopes other
|
||
then SCOPE_ENTITY (Linbin Chen & Frank Wesemann via hossman)
|
||
|
||
* SOLR-3042: Fixed Maven Jetty plugin configuration.
|
||
(David Smiley via Steve Rowe)
|
||
|
||
* SOLR-2970: CSV ResponseWriter returns fields defined as stored=false in schema (janhoy)
|
||
|
||
* LUCENE-3690, LUCENE-2208, SOLR-882, SOLR-42: Re-implemented
|
||
HTMLStripCharFilter as a JFlex-generated scanner. See below for a list
|
||
of bug fixes and other changes. To get the same behavior as
|
||
HTMLStripCharFilter in Solr version 3.5 and earlier (including the bugs),
|
||
use LegacyHTMLStripCharFilter, which is the previous implementation.
|
||
|
||
Behavior changes from the previous version:
|
||
|
||
- Known offset bugs are fixed.
|
||
- The "Mark invalid" exceptions reported in SOLR-1283 are no longer
|
||
triggered (the bug is still present in LegacyHTMLStripCharFilter).
|
||
- The character entity "'" is now always properly decoded.
|
||
- More cases of <script> tags are now properly stripped.
|
||
- CDATA sections are now handled properly.
|
||
- Valid tag name characters now include the supplementary Unicode characters
|
||
from Unicode character classes [:ID_Start:] and [:ID_Continue:].
|
||
- Uppercase character entities """, "©", ">", "<", "®",
|
||
and "&" are now recognized and handled as if they were in lowercase.
|
||
- The REPLACEMENT CHARACTER U+FFFD is now used to replace numeric character
|
||
entities for unpaired UTF-16 low and high surrogates (in the range
|
||
[U+D800-U+DFFF]).
|
||
- Properly paired numeric character entities for UTF-16 surrogates are now
|
||
converted to the corresponding code units.
|
||
- Opening tags with unbalanced quotation marks are now properly stripped.
|
||
- Literal "<" and ">" characters in opening tags, regardless of whether they
|
||
appear inside quotation marks, now inhibit recognition (and stripping) of
|
||
the tags. The only exception to this is for values of event-handler
|
||
attributes, e.g. "onClick", "onLoad", "onSelect".
|
||
- A newline '\n' is substituted instead of a space for stripped HTML markup.
|
||
- Nothing is substituted for opening and closing inline tags - they are
|
||
simply removed. The list of inline tags is (case insensitively): <a>,
|
||
<abbr>, <acronym>, <b>, <basefont>, <bdo>, <big>, <cite>, <code>, <dfn>,
|
||
<em>, <font>, <i>, <img>, <input>, <kbd>, <label>, <q>, <s>, <samp>,
|
||
<select>, <small>, <span>, <strike>, <strong>, <sub>, <sup>, <textarea>,
|
||
<tt>, <u>, and <var>.
|
||
- HTMLStripCharFilterFactory now handles HTMLStripCharFilter's "escapedTags"
|
||
feature: opening and closing tags with the given names, including any
|
||
attributes and their values, are left intact in the output.
|
||
(Steve Rowe)
|
||
|
||
* LUCENE-3717: Fixed offset bugs in TrimFilter, WordDelimiterFilter, and
|
||
HyphenatedWordsFilter where they would create invalid offsets in
|
||
some situations, leading to problems in highlighting. (Robert Muir)
|
||
|
||
* SOLR-2280: commitWithin ignored for a delete query (Juan Grande via janhoy)
|
||
|
||
* SOLR-3073: Fixed 'Invalid UUID string' error when having an UUID field as
|
||
the unique key and executing a distributed grouping request. (Devon Krisman, Martijn van Groningen)
|
||
|
||
* SOLR-3084: Fixed initialization error when using
|
||
<queryResponseWriter default="true" ... /> (Bernd Fehling and hossman)
|
||
|
||
* SOLR-3109: Fixed numerous redundant shard requests when using distributed grouping.
|
||
(rblack via Martijn van Groningen)
|
||
|
||
* SOLR-3052: Fixed typo in distributed grouping parameters.
|
||
(Martijn van Groningen, Grant Ingersoll)
|
||
|
||
* SOLR-2909: Add support for ResourceLoaderAware tokenizerFactories in synonym
|
||
filter factories. (Tom Klonikowski, Jun Ohtani via Koji Sekiguchi)
|
||
|
||
* SOLR-3168: ReplicationHandler "numberToKeep" & "maxNumberOfBackups" parameters
|
||
would keep only 1 backup, even if more than 1 was specified (Neil Hooey, James Dyer)
|
||
|
||
* SOLR-3009: hitGrouped.vm isn't shipped with 3.x (ehatcher, janhoy)
|
||
|
||
* SOLR-3195: timeAllowed is ignored for grouping queries
|
||
(Russell Black via Martijn van Groningen)
|
||
|
||
* SOLR-2124: Do not log stack traces for "Service Disabled" / 503 Exceptions (PingRequestHandler, etc)
|
||
(James Dyer, others)
|
||
|
||
* SOLR-3260: DataImportHandler: ScriptTransformer gives better error messages when
|
||
problems arise on initalization (no Script Engine, invalid script, etc). (James Dyer)
|
||
|
||
* SOLR-2959: edismax now respects the magic fields '_val_' and '_query_'
|
||
(Michael Watts, hossman)
|
||
|
||
* SOLR-3074: fix SolrPluginUtils.docListToSolrDocumentList to respect the
|
||
list of fields specified. This fix also deprecates
|
||
DocumentBuilder.loadStoredFields which is not used anywhere in Solr,
|
||
and was fundamentally broken/bizarre.
|
||
(hossman, Ahmet Arslan)
|
||
|
||
* SOLR-3264: Fix CoreContainer and SolrResourceLoader logging to be more
|
||
clear about when SolrCores are being created, and stop misleading people
|
||
about SolrCore instanceDir's being the "Solr Home Dir" (hossman)
|
||
|
||
* SOLR-3046: Fix whitespace typo in DIH response "Time taken" (hossman)
|
||
|
||
* SOLR-3261: Fix edismax to respect query operators when literal colons
|
||
are used in query string. (Juan Grande via hossman)
|
||
|
||
* SOLR-3226: Fix SignatureUpdateProcessor to no longer ignore non-String
|
||
field values (Spyros Kapnissis, hossman)
|
||
|
||
* SOLR-3200: Fix SignatureUpdateProcessor "all fields" mode to use all
|
||
fields of each document instead of the fields specified by the first
|
||
document indexed (Spyros Kapnissis via hossman)
|
||
|
||
* SOLR-3316: Distributed grouping failed when rows parameter was set to 0 and sometimes returned a wrong
|
||
hit count as matches. (Cody Young, Martijn van Groningen)
|
||
|
||
Other Changes
|
||
----------------------
|
||
* SOLR-2922: Upgrade commons-io and commons-lang to 2.1 and 2.6, respectively. (koji)
|
||
|
||
* SOLR-2920: Refactor frequent conditional use of DefaultSolrParams and
|
||
AppendedSolrParams into factory methods.
|
||
(David Smiley via hossman)
|
||
|
||
* SOLR-3032: Deprecate logOnce from SolrException logOnce and all the supporting
|
||
structure will disappear in 4.0. Errors should be caught and logged at the
|
||
top-most level or logged and NOT propagated up the chain. (Erick Erickson)
|
||
|
||
* SOLR-2718: Add ability to lazy load response writers, defined with startup="lazy".
|
||
(ehatcher)
|
||
|
||
* SOLR-2901: Upgrade Solr to Tika 1.0 (janhoy)
|
||
|
||
* SOLR-3059: Example XSL stylesheet for indexing query result XML (janhoy)
|
||
|
||
* SOLR-3097, SOLR-3105: Add analysis configurations for different languages to
|
||
the example. (Christian Moen, Robert Muir)
|
||
|
||
* SOLR-3005: Default QueryResponseWriters are now initialized via init() with an empty
|
||
NamedList. (Gasol Wu, Chris Male)
|
||
|
||
* SOLR-3140: Upgrade schema version to 1.5, where omitNorms defaults to "true" for all
|
||
primitive (non-analyzed) field types such as int, float, date, bool, string.. (janhoy)
|
||
|
||
* SOLR-3077: Better error messages when attempting to use "blank" field names
|
||
(Antony Stubbs via hossman)
|
||
|
||
* SOLR-2712: expecting fl=score to return all fields is now deprecated.
|
||
In solr 4.0, this will only return the score. (ryan)
|
||
|
||
* SOLR-3156: Check for Lucene directory locks at startup. In previous versions
|
||
this check was only performed during modifying (e.g. adding and deleting
|
||
documents) the index. (Luca Cavanna via Martijn van Groningen)
|
||
|
||
* SOLR-1052: Deprecated <indexDefaults> and <mainIndex> in solrconfig.xml
|
||
From now, all settings go in the new <indexConfig> tag, and some defaults are
|
||
changed: useCompoundFile=false, ramBufferSizeMB=32, lockType=native, so that
|
||
the effect of NOT specifying <indexConfig> at all gives same result as the
|
||
example config used to give in 3.5 (janhoy, gsingers)
|
||
|
||
Build
|
||
----------------------
|
||
* SOLR-2487: Add build target to package war without slf4j jars (janhoy)
|
||
|
||
* SOLR-3112: Fix tests not to write to src/test-files (Luca Cavanna via Robert Muir)
|
||
|
||
* LUCENE-3753: Restructure the Solr build system. (Steve Rowe)
|
||
|
||
* SOLR-3204: The packaged pre-release artifact of Commons CSV used the original
|
||
package name (org.apache.commons.csv). This created a compatibility issue as
|
||
the Apache Commons team works toward an official release of Commons CSV.
|
||
The source of Commons CSV was added under a separate package name to the

* SOLR-2742: SolrJ: Provide commitWithinMs as optional parameter for all add() methods,
|
||
making the feature more conveniently accessible for developers (janhoy)
|
||
|
||
Bug Fixes
|
||
----------------------
|
||
* SOLR-2748: The CommitTracker used for commitWith or autoCommit by maxTime
|

registered. (yonik)
|
||
|
||

|
||
open if the executor rejects a task. (Mark Miller)
|
||
|

* SOLR-2791: Replication: abortfetch command is broken if replication was started
|
||
by fetchindex command instead of a regular poll (Yury Kats via shalin)

|
||
can not be parsed as numbers for Trie fields. (Jeff Crump and hossman)
|
||
|
||
* SOLR-2902: List of collations are wrong parsed in SpellCheckResponse causing
|
||
a wrong number of collation results in the response.
|
||
(Bastiaan Verhoef, James Dyer via Simon Willnauer)
|
||
|
||
Other Changes
|
||
----------------------
|
||
|
||
* SOLR-2750: Make both "update.chain" and the deprecated "update.param" work
|
||
consistently everywhere; see also SOLR-2105. (Mark Miller, janhoy)
|
||
|
||
* LUCENE-3410: Deprecated the WordDelimiterFilter constructors accepting multiple

|
||
bitfield (Chris Male)
|
||
|
||
* SOLR-2758: Moved ConcurrentLRUCache from o.a.s.common.util package in the solrj

(Steve Rowe, Mike McCandless)
|
||
|
||
* SOLR-2771: Solr modules' tests should not depend on solr-core test classes;

|
||
|
||
================== 3.4.0 ==================
|
||
|
||
Upgrading from Solr 3.3
|
||
----------------------
|
||
|
||
* The Lucene index format has changed and as a result, once you upgrade,
|
||
previous versions of Solr will no longer be able to read your indices.
|
||
In a master/slave configuration, all searchers/slaves should be upgraded
|
||
before the master. If the master were to be updated first, the older
|
||
searchers would not be able to read the new index format.
|
||
|
||
* Previous versions of Solr silently allow and ignore some contradictory
|
||
properties specified in schema.xml. For example:
|
||
- indexed="false" omitNorms="false"
|
||
- indexed="false" omitTermFreqAndPositions="false"
|
||
Field property validation has now been fixed, to ensure that
|
||
contradictions like these now generate error messages. If users
|
||
have existing schemas that generate one of these new "conflicting
|
||
'false' field options for non-indexed field" error messages the
|
||
conflicting "omit*" properties can safely be removed, or changed to
|
||
"true" for consistent behavior with previous Solr versions. This
|
||
situation has now been fixed to cause an error on startup when these
|
||
contradictory options. See SOLR-2669.
|
||
|
||
* FacetComponent no longer catches and embeds exceptions occurred during facet
|
||
processing, it throws HTTP 400 or 500 exceptions instead.
|
||
|
||
New Features
|
||
----------------------
|
||
|
||
* SOLR-2540: CommitWithin as an Update Request parameter
|
||
You can now specify &commitWithin=N (ms) on the update request (janhoy)
|
||
|
||
* SOLR-2458: post.jar enhanced to handle JSON, CSV and <optimize> (janhoy)
|
||
|
||
* LUCENE-3234: add a new parameter hl.phraseLimit for FastVectorHighlighter speed up.
|
||
(Mike Sokolov via koji)
|
||
|
||
* SOLR-2429: Ability to add cache=false to queries and query filters to avoid
|
||
using the filterCache or queryCache. A cost may also be specified and is used
|
||
to order the evaluation of non-cached filters from least to greatest cost .
|
||
For very expensive query filters (cost >= 100) if the query implements
|
||
the PostFilter interface, it will be used to obtain a Collector that is
|
||
checked only for documents that match the main query and all other filters.
|
||
The "frange" query now implements the PostFilter interface. (yonik)
|
||
|
||
* SOLR-2630: Added new XsltUpdateRequestHandler that works like
|
||
XmlUpdateRequestHandler but allows to transform the POSTed XML document
|
||
using XSLT. This allows to POST arbitrary XML documents to the update
|
||
handler, as long as you also provide a XSL to transform them to a valid
|
||
Solr input document. (Upayavira, Uwe Schindler)
|
||
|
||
* SOLR-2615: Log individual updates (adds and deletes) at the FINE level
|
||
before adding to the index. Fix a null pointer exception in logging
|
||
when there was no unique key. (David Smiley via yonik)
|
||
|
||
* LUCENE-2048: Added omitPositions to the schema, so you can omit position
|
||
information while still indexing term frequencies. (rmuir)
|
||
|
||
* SOLR-2584: add UniqFieldsUpdateProcessor that removes duplicate values in the
|
||
specified fields. (Elmer Garduno, koji)
|
||
|
||
* SOLR-2670: Added NIOFSDirectoryFactory (yonik)
|
||
|
||
* SOLR-2523: Added support in SolrJ to easily interact with range facets.
|
||
The range facet response can be parsed and is retrievable from the
|
||
QueryResponse class. The SolrQuery class has convenient methods for using
|
||
range facets. (Martijn van Groningen)
|
||
|
||
* SOLR-2637: Added support for group result parsing in SolrJ.
|
||
(Tao Cheng, Martijn van Groningen)
|
||
|
||
* SOLR-2665: Added post group faceting. Facet counts are based on the most
|
||
relevant document of each group matching the query. This feature has the
|
||
same impact on the StatsComponent. (Martijn van Groningen)
|
||
|
||
* SOLR-2675: CoreAdminHandler now allows arbitrary properties to be
|
||
specified when CREATEing a new SolrCore using property.* request
|
||
params. (Yury Kats, hossman)
|
||
|
||
* SOLR-2714: JSON update format - "null" field values are now dropped
|
||
instead of causing an exception. (Trygve Laugstøl, yonik)
|
||
|
||
|
||
Optimizations
|
||
----------------------
|
||
|
||
* LUCENE-3233: Improved memory usage, build time, and performance of
|
||
SynonymFilterFactory. (Mike McCandless, Robert Muir)
|
||
|
||
Bug Fixes
|
||
----------------------
|
||
|
||
* SOLR-2625: TermVectorComponent throws NPE if TF-IDF option is used without DF
|
||
option. (Daniel Erenrich, Simon Willnauer)
|
||
|
||
* SOLR-2631: PingRequestHandler should not allow to ping itsself using "qt"
|
||
param to prevent infinite loop. (Edoardo Tosca, Uwe Schindler)
|
||
|
||
* SOLR-2636: Fix explain functionality for negative queries. (Tom Hill via yonik)
|
||
|
||
* SOLR-2538: Range Faceting on long/double fields could overflow if values
|
||
bigger then the max int/float were used.
|
||
(Erbi Hanka, hossman)
|
||
|
||
* SOLR-2230: CommonsHttpSolrServer.addFile could not be used to send
|
||
multiple files in a single request.
|
||
(Stephan Günther, hossman)
|
||
|
||
* SOLR-2541: PluginInfos was not correctly parsing <long/> tags when
|
||
initializing plugins
|
||
(Frank Wesemann, hossman)
|
||
|
||
* SOLR-2623: Solr JMX MBeans do not survive core reloads (Alexey Serba, shalin)
|
||
|
||
* Fixed grouping bug when start is bigger than rows and format is simple that zero documents are returned even
|
||
if there are documents to display. (Martijn van Groningen, Nikhil Chhaochharia)
|
||
|
||
* SOLR-2564: Fixed ArrayIndexOutOfBoundsException when using simple format and
|
||
start > 0 (Martijn van Groningen, Matteo Melli)
|
||
|
||
* SOLR-2642: Fixed sorting by function when using grouping. (Thomas Heigl, Martijn van Groningen)
|
||
|
||
* SOLR-2535: REGRESSION: in Solr 3.x and trunk the admin/file handler
|
||
fails to show directory listings (David Smiley, Peter Wolanin via Erick Erickson)
|
||
|
||
* SOLR-2545: ExternalFileField file parsing would fail if any key
|
||
contained an "=" character. It now only looks for the last "=" delimiter
|
||
prior to the float value.
|
||
(Markus Jelsma, hossman)
|
||
|
||
* SOLR-2662: When Solr is configured to have no queryResultCache, the
|
||
"start" parameter was not honored and the documents returned were
|
||
0 through start+offset. (Markus Jelsma, yonik)
|
||
|
||
* SOLR-2669: Fix backwards validation of field properties in
|
||
SchemaField.calcProps (hossman)
|
||
|
||
* SOLR-2676: Add "welcome-file-list" to solr.war so admin UI works correctly
|
||
in servlet containers such as WebSphere that do not use a default list
|
||
(Jay R. Jaeger, hossman)
|
||
|
||
* SOLR-2606: Fixed sort parsing of fields containing punctuation that
|
||
failed due to sort by function changes introduced in SOLR-1297
|
||
(Mitsu Hadeishi, hossman)
|
||
|
||
Other Changes
|
||
----------------------
|
||
|
||
* SOLR-2629: Eliminate deprecation warnings in some JSPs.
|
||
(Bernd Fehling, hossman)
|
||
|
||
Build
|
||
----------------------
|
||
|
||
* SOLR-2452,SOLR-2653,LUCENE-3323,SOLR-2659,LUCENE-3329,SOLR-2666:
|
||
Rewrote the Solr build system:
|
||
- Integrated more fully with the Lucene build system: generalized the
|
||
Lucene build system and eliminated duplication.
|
||
- Converted all Solr contribs to the Lucene/Solr conventional src/ layout:
|
||
java/, resources/, test/, and test-files/<contrib-name>.
|
||
- Created a new Solr-internal module named "core" by moving the java/,
|
||
test/, and test-files/ directories from solr/src/ to solr/core/src/.
|
||
- Merged solr/src/webapp/src/ into solr/core/src/java/.
|
||
- Eliminated solr/src/ by moving all its directories up one level;
|
||
renamed solr/src/site/ to solr/site-src/ because solr/site/ already
|
||
exists.
|
||
- Merged solr/src/common/ into solr/solrj/src/java/.
|
||
- Moved o.a.s.client.solrj.* and o.a.s.common.* tests from
|
||
solr/src/test/ to solr/solrj/src/test/.
|
||
- Made the solrj tests not depend on the solr core tests by moving
|
||
some classes from solr/src/test/ to solr/test-framework/src/java/.
|
||
- Each internal module (core/, solrj/, test-framework/, and webapp/)
|
||
now has its own build.xml, from which it is possible to run
|
||
module-specific targets. solr/build.xml delegates all build
|
||
tasks (via <ant dir="internal-module-dir"> calls) to these
|
||
modules' build.xml files.
|
||
(Steve Rowe, Robert Muir)
|
||
|
||
* LUCENE-3406: Add ant target 'package-local-src-tgz' to Lucene and Solr
|
||
to package sources from the local working copy.
|
||
(Seung-Yeoul Yang via Steve Rowe)

Documentation
|
||
----------------------
|
||
|
||
================== 3.3.0 ==================
|
||
|
||
Upgrading from Solr 3.2.0
|
||
----------------------
|
||
* SolrCore's CloseHook API has been changed in a backward-incompatible way. It
|
||
has been changed from an interface to an abstract class. Any custom
|
||
components which use the SolrCore.addCloseHook method will need to
|
||
be modified accordingly. To migrate, put your old CloseHook#close impl into
|
||
CloseHook#preClose.
|
||
|
||
New Features
|
||
----------------------
|
||
|
||
* SOLR-2378: A new, automaton-based, implementation of suggest (autocomplete)
|
||
component, offering an order of magnitude smaller memory consumption
|
||
compared to ternary trees and jaspell and very fast lookups at runtime.
|
||
(Dawid Weiss)
|
||
|
||
* SOLR-2400: Field- and DocumentAnalysisRequestHandler now provide a position
|
||
history for each token, so you can follow the token through all analysis stages.
|
||
The output contains a separate int[] attribute containing all positions from
|
||
previous Tokenizers/TokenFilters (called "positionHistory").
|
||
(Uwe Schindler)
|
||
|
||
* SOLR-2524: (SOLR-236, SOLR-237, SOLR-1773, SOLR-1311) Grouping / Field collapsing
|
||
using the Lucene grouping contrib. The search result can be grouped by field and query.
|

Harish Agarwal, yonik, Michael McCandless, Bill Bell)
|
||
|
||
* SOLR-1331 -- Added a srcCore parameter to CoreAdminHandler's mergeindexes action
|
||
to merge one or more cores' indexes to a target core (shalin)
|
||
|
||
* SOLR-2610 -- Add an option to delete index through CoreAdmin UNLOAD action (shalin)
|
||
|
||
Optimizations
|
||
----------------------
|
||
|
||
* SOLR-2567: Solr now defaults to TieredMergePolicy. See http://s.apache.org/merging
|
||
for more information. (rmuir)
|
||
|
||
Bug Fixes
|
||
----------------------
|
||
|
||
* SOLR-2519: Improve text_* fieldTypes in example schema.xml: improve
|
||
cross-language defaults for text_general; break out separate
|
||
English-specific fieldTypes (Jan Høydahl, hossman, Robert Muir,
|
||
yonik, Mike McCandless)
|
||
|
||
* SOLR-2462: Fix extremely high memory usage problems with spellcheck.collate.
|
||
Separately, an additional spellcheck.maxCollationEvaluations (default=10000)
|
||
parameter is added to avoid excessive CPU time in extreme cases (e.g. long
|
||
queries with many misspelled words). (James Dyer via rmuir)
|
||
|
||
Other Changes
|
||
----------------------
|
||
|
||
* SOLR-2571: Add a commented out example of the spellchecker's thresholdTokenFrequency
|
||
parameter to the example solrconfig.xml, and also add a unit test for this feature.
|
||
(James Dyer via rmuir)
|
||
|
||
* SOLR-2576: Deprecate SpellingResult.add(Token token, int docFreq), please use
|
||
SpellingResult.addFrequency(Token token, int docFreq) instead.
|
||
(James Dyer via rmuir)
|
||
|
||
* SOLR-2574: Upgrade slf4j to v1.6.1 (shalin)
|
||
|
||
* LUCENE-3204: The maven-ant-tasks jar is now included in the source tree;
|
||
users of the generate-maven-artifacts target no longer have to manually
|
||
place this jar in the Ant classpath. NOTE: when Ant looks for the
|
||
maven-ant-tasks jar, it looks first in its pre-existing classpath, so
|
||
any copies it finds will be used instead of the copy included in the
|
||
Lucene/Solr source tree. For this reason, it is recommeded to remove
|
||
any copies of the maven-ant-tasks jar in the Ant classpath, e.g. under
|
||
~/.ant/lib/ or under the Ant installation's lib/ directory. (Steve Rowe)
|
||
|
||
* SOLR-2611: Fix typos in the example configuration (Eric Pugh via rmuir)
|
||

Upgrading from Solr 3.1
|
||
----------------------
|
||
|
||
* The updateRequestProcessorChain for a RequestHandler is now defined
|

with update.chain rather than update.processor. The latter still works,
|
||
but has been deprecated.
|
||
|
||
Detailed Change List
|
||
----------------------
|
||
|
||
New Features
|
||
----------------------
|
||
|
||
* SOLR-2496: Add ability to specify overwrite and commitWithin as request
|
||
parameters (e.g. specified in the URL) when using the JSON update format,
|
||
and added a simplified format for specifying multiple documents.
|
||
Example: [{"id":"doc1"},{"id":"doc2"}]
|
||
(yonik)
|
||
|
||
* SOLR-2113: Add TermQParserPlugin, registered as "term". This is useful
|
||
when generating filter queries from terms returned from field faceting or
|
||
the terms component. Example: fq={!term f=weight}1.5 (hossman, yonik)
|
||
|
||
* SOLR-1915: DebugComponent now supports using a NamedList to model
|
||
Explanation objects in it's responses instead of
|
||
Explanation.toString (hossman)
|
||
|
||
Optimizations
|
||
----------------------
|
||
|
||
Bug Fixes
|
||
----------------------
|
||
|
||
* SOLR-2445: Change the default qt to blank in form.jsp, because there is no "standard"
|
||
request handler unless you have it in your solrconfig.xml explicitly. (koji)
|
||
|
||
* SOLR-2455: Prevent double submit of forms in admin interface.
|
||
(Jeffrey Chang via uschindler)
|
||
|
||
* SOLR-2464: Fix potential slowness in QueryValueSource (the query() function) when
|
||
the query is very sparse and may not match any documents in a segment. (yonik)
|
||
|
||
* SOLR-2469: When using java replication with replicateAfter=startup, the first
|
||
commit point on server startup is never removed. (yonik)
|
||
|
||
* SOLR-2466: SolrJ's CommonsHttpSolrServer would retry requests on failure, regardless
|
||
of the configured maxRetries, due to HttpClient having it's own retry mechanism
|
||
by default. The retryCount of HttpClient is now set to 0, and SolrJ does
|
||
the retry. (yonik)
|
||
|
||
* SOLR-2409: edismax parser - treat the text of a fielded query as a literal if the
|
||
fieldname does not exist. For example Mission: Impossible should not search on
|
||
the "Mission" field unless it's a valid field in the schema. (Ryan McKinley, yonik)
|
||
|
||
* SOLR-2403: facet.sort=index reported incorrect results for distributed search
|
||
in a number of scenarios when facet.mincount>0. This patch also adds some
|
||
performance/algorithmic improvements when (facet.sort=count && facet.mincount=1
|
||
&& facet.limit=-1) and when (facet.sort=index && facet.mincount>0) (yonik)
|
||
|
||
* SOLR-2333: The "rename" core admin action does not persist the new name to solr.xml
|
||
(Rasmus Hahn, Paul R. Brown via Mark Miller)
|
||
|
||
* SOLR-2390: Performance of usePhraseHighlighter is terrible on very large Documents,
|
||
regardless of hl.maxDocCharsToAnalyze. (Mark Miller)
|
||
|
||
* SOLR-2474: The helper TokenStreams in analysis.jsp and AnalysisRequestHandlerBase
|
||
did not clear all attributes so they displayed incorrect attribute values for tokens
|
||
in later filter stages. (uschindler, rmuir, yonik)
|
||
|
||
* SOLR-2467: Fix <analyzer class="..." /> initialization so any errors
|
||
are logged properly. (hossman)
|
||
|
||
* SOLR-2493: SolrQueryParser was fixed to not parse the SolrConfig DOM tree on each
|
||
instantiation which is a huge slowdown. (Stephane Bailliez via uschindler)
|
||
|
||
* SOLR-2495: The JSON parser could hang on corrupted input and could fail
|
||
to detect numbers that were too large to fit in a long. (yonik)
|
||
|
||
* SOLR-2520: Make JSON response format escape \u2029 as well as \u2028
|
||
in strings since those characters are not valid in javascript strings
|
||
(although they are valid in JSON strings). (yonik)
|
||
|
||
* SOLR-2536: Add ReloadCacheRequestHandler to fix ExternalFileField bug (if reopenReaders
|
||
set to true and no index segments have been changed, commit cannot trigger reload
|
||
external file). (koji)
|
||
|
||
* SOLR-2539: VectorValueSource.floatVal incorrectly used byteVal on sub-sources.
|
||
(Tom Liu via yonik)
|
||
|
||
* SOLR-2554: RandomSortField didn't work when used in a function query. (yonik)
|
||
|
||
|
||
Other Changes
|
||
----------------------
|
||
|
||
* SOLR-2061: Pull base tests out into a new Solr Test Framework module,
|
||
and publish binary, javadoc, and source test-framework jars.
|
||
(Drew Farris, Robert Muir, Steve Rowe)
|
||
|
||
* SOLR-2105: Rename RequestHandler param 'update.processor' to 'update.chain'.
|
||
(Jan Høydahl via Mark Miller)
|
||
|
||
* SOLR-2485: Deprecate BaseResponseWriter, GenericBinaryResponseWriter, and
|
||
GenericTextResponseWriter. These classes will be removed in 4.0. (ryan)
|
||
|
||
* SOLR-2451: Enhance assertJQ to allow individual tests to specify the
|
||
tolerance delta used in numeric equalities. This allows for slight
|
||
variance in asserting score comparisons in unit tests.
|
||
(David Smiley, Chris Hostetter)
|
||
|
||
* SOLR-2528: Remove default="true" from HtmlEncoder in example solrconfig.xml,
|
||
because html encoding confuses non-ascii users. (koji)
|
||
|
||
Build
|
||
----------------------
|
||
|
||
* LUCENE-3006: Building javadocs will fail on warnings by default. Override with -Dfailonjavadocwarning=false (sarowe, gsingers)
|
||
|
||
|
||
Documentation
|

----------------------
|

|
||
|

================== 3.1.0 ==================
|
||
Versions of Major Components
|
||
---------------------
|
||
Apache Lucene 3.1.0
|
||
Apache Tika 0.8
|
||
Carrot2 3.4.2
|
||
Velocity 1.6.1 and Velocity Tools 2.0-beta3
|

Apache UIMA 2.3.1-SNAPSHOT
|
||
|
||
|
||
Upgrading from Solr 1.4
|
||
----------------------
|
||
|
||
* The Lucene index format has changed and as a result, once you upgrade,
|
||
previous versions of Solr will no longer be able to read your indices.
|
||
In a master/slave configuration, all searchers/slaves should be upgraded
|
||
before the master. If the master were to be updated first, the older
|
||
searchers would not be able to read the new index format.
|
||
|
||
* The Solr JavaBin format has changed as of Solr 3.1. If you are using the
|
||
JavaBin format, you will need to upgrade your SolrJ client. (SOLR-2034)
|
||
|
||
* The experimental ALIAS command has been removed (SOLR-1637)
|
||
|
||
* Using solr.xml is recommended for single cores also (SOLR-1621)
|
||
|
||
* Old syntax of <highlighting> configuration in solrconfig.xml
|
||
is deprecated (SOLR-1696)
|
||
|
||
* The deprecated HTMLStripReader, HTMLStripWhitespaceTokenizerFactory and
|
||
HTMLStripStandardTokenizerFactory were removed. To strip HTML tags,
|
||
HTMLStripCharFilter should be used instead, and it works with any
|
||
Tokenizer of your choice. (SOLR-1657)
|
||
|
||
* Field compression is no longer supported. Fields that were formerly
|
||
compressed will be uncompressed as index segments are merged. For
|
||
shorter fields, this may actually be an improvement, as the compression
|
||
used was not very good for short text. Some indexes may get larger though.
|
||
|
||
* SOLR-1845: The TermsComponent response format was changed so that the
|
||
"terms" container is a map instead of a named list. This affects
|
||
response formats like JSON, but not XML. (yonik)
|
||
|
||
* SOLR-1876: All Analyzers and TokenStreams are now final to enforce
|
||
the decorator pattern. (rmuir, uschindler)
|
||
|
||
* LUCENE-2608: Added the ability to specify the accuracy on a per request basis.
|
||
It is recommended that implementations of SolrSpellChecker should change over to the new SolrSpellChecker
|
||
methods using the new SpellingOptions class, but are not required to. While this change is
|
||
backward compatible, the trunk version of Solr has already dropped support for all but the SpellingOptions method. (gsingers)
|
||
|
||
* readercycle script was removed. (SOLR-2046)
|
||
|
||
* In previous releases, sorting or evaluating function queries on
|
||
fields that were "multiValued" (either by explicit declaration in
|
||
schema.xml or by implict behavior because the "version" attribute on
|
||
the schema was less then 1.2) did not generally work, but it would
|
||
sometimes silently act as if it succeeded and order the docs
|
||
arbitrarily. Solr will now fail on any attempt to sort, or apply a
|
||
function to, multi-valued fields
|
||
|
||
* The DataImportHandler jars are no longer included in the solr
|
||
WAR and should be added in Solr's lib directory, or referenced
|
||
via the <lib> directive in solrconfig.xml.
|
||
|
||
|
||
Detailed Change List
|
||
----------------------
|
||
|
||
New Features
|
||
----------------------
|
||
|
||
* SOLR-1302: Added several new distance based functions, including
|
||
Great Circle (haversine), Manhattan, Euclidean and String (using the
|
||
StringDistance methods in the Lucene spellchecker).
|
||
Also added geohash(), deg() and rad() convenience functions.
|
||
See http://wiki.apache.org/solr/FunctionQuery. (gsingers)
|
||
|
||
* SOLR-1553: New dismax parser implementation (accessible as "edismax")
|
||
that supports full lucene syntax, improved reserved char escaping,
|
||
fielded queries, improved proximity boosting, and improved stopword
|
||
handling. Note: status is experimental for now. (yonik)
|
||
|
||
* SOLR-1574: Add many new functions from java Math (e.g. sin, cos) (yonik)
|
||
|
||
* SOLR-1569: Allow functions to take in literal strings by modifying the
|
||
FunctionQParser and adding LiteralValueSource (gsingers)
|
||
|
||
* SOLR-1571: Added unicode collation support though Lucene's CollationKeyFilter
|
||
(Robert Muir via shalin)
|
||
|
||
* SOLR-785: Distributed Search support for SpellCheckComponent
|
||
(Matthew Woytowitz, shalin)
|
||
|
||
* SOLR-1625: Add regexp support for TermsComponent (Uri Boness via noble)
|
||
|
||
* SOLR-1297: Add sort by Function capability (gsingers, yonik)
|
||
|
||
* SOLR-1139: Add TermsComponent Query and Response Support in SolrJ (Matt Weber via shalin)
|
||
|
||
* SOLR-1177: Distributed Search support for TermsComponent (Matt Weber via shalin)
|
||
|
||
* SOLR-1621, SOLR-1722: Allow current single core deployments to be specified by solr.xml (Mark Miller , noble)
|
||
|
||
* SOLR-1532: Allow StreamingUpdateSolrServer to use a provided HttpClient (Gabriele Renzi via shalin)
|
||
|
||
* SOLR-1653: Add PatternReplaceCharFilter (koji)
|
||
|
||
* SOLR-1131: FieldTypes can now output multiple Fields per Type and still be searched. This can be handy for hiding the details of a particular
|
||
implementation such as in the spatial case. (Chris Mattmann, shalin, noble, gsingers, yonik)
|
||
|
||
* SOLR-1586: Add support for Geohash and Spatial Tile FieldType (Chris Mattmann, gsingers)
|
||
|
||
* SOLR-1697: PluginInfo should load plugins w/o class attribute also (noble)
|
||
|
||
* SOLR-1268: Incorporate FastVectorHighlighter (koji)
|
||
|
||
* SOLR-1750: SolrInfoMBeanHandler added for simpler programmatic access
|
||
to info currently available from registry.jsp and stats.jsp
|
||
(ehatcher, hossman)
|
||
|
||
* SOLR-1815: SolrJ now preserves the order of facet queries. (yonik)
|
||
|
||
* SOLR-1677: Add support for choosing the Lucene Version for Lucene components within
|
||
Solr. (Uwe Schindler, Mark Miller)
|
||
|
||
* SOLR-1379: Add RAMDirectoryFactory for non-persistent in memory index storage.
|
||
(Alex Baranov via yonik)
|
||
|
||
* SOLR-1857: Synced Solr analysis with Lucene 3.1. Added KeywordMarkerFilterFactory
|
||
and StemmerOverrideFilterFactory, which can be used to tune stemming algorithms.
|
||
Added factories for Bulgarian, Czech, Hindi, Turkish, and Wikipedia analysis. Improved the
|
||
performance of SnowballPorterFilterFactory. (rmuir)
|
||
|
||
* SOLR-1657: Converted remaining TokenStreams to the Attributes-based API. All Solr
|
||
TokenFilters now support custom Attributes, and some have improved performance:
|
||
especially WordDelimiterFilter and CommonGramsFilter. (rmuir, cmale, uschindler)
|
||
|
||
* SOLR-1740: ShingleFilterFactory supports the "minShingleSize" and "tokenSeparator"
|
||
parameters for controlling the minimum shingle size produced by the filter, and
|
||
the separator string that it uses, respectively. (Steven Rowe via rmuir)
|
||
|
||
* SOLR-744: ShingleFilterFactory supports the "outputUnigramsIfNoShingles"
|
||
parameter, to output unigrams if the number of input tokens is fewer than
|
||
minShingleSize, and no shingles can be generated.
|
||
(Chris Harris via Steven Rowe)
|
||
|
||
* SOLR-1923: PhoneticFilterFactory now has support for the
|
||
Caverphone algorithm. (rmuir)
|
||
|
||
* SOLR-1957: The VelocityResponseWriter contrib moved to core.
|
||
Example search UI now available at http://localhost:8983/solr/browse
|
||
(ehatcher)
|
||
|
||
* SOLR-1974: Add LimitTokenCountFilterFactory. (koji)
|
||
|
||
* SOLR-1966: QueryElevationComponent can now return just the included results in the elevation file (gsingers, yonik)
|
||
|
||
* SOLR-1556: TermVectorComponent now supports per field overrides. Also, it now throws an error
|
||
if passed in fields do not exist and warnings
|
||
if fields that do not have term vector options (termVectors, offsets, positions)
|
||
that align with the schema declaration. It also
|
||
will now return warnings about (gsingers)
|
||
|
||
* SOLR-1985: FastVectorHighlighter: add wrapper class for Lucene's SingleFragListBuilder (koji)
|
||
|
||
* SOLR-1984: Add HyphenationCompoundWordTokenFilterFactory. (PB via rmuir)
|
||
|
||
* SOLR-397: Date Faceting now supports a "facet.date.include" param
|
||
for specifying when the upper & lower end points of computed date
|
||
ranges should be included in the range. Legal values are: "all",
|
||
"lower", "upper", "edge", and "outer". For backwards compatibility
|
||
the default value is the set: [lower,upper,edge], so that all ranges
|
||
between start and end are inclusive of their endpoints, but the
|
||
"before" and "after" ranges are not.
|
||
|
||
* SOLR-945: JSON update handler that accepts add, delete, commit
|
||
commands in JSON format. (Ryan McKinley, yonik)
|
||
|
||
* SOLR-2015: Add a boolean attribute autoGeneratePhraseQueries to TextField.
|
||
autoGeneratePhraseQueries="true" (the default) causes the query parser to
|
||
generate phrase queries if multiple tokens are generated from a single
|
||
non-quoted analysis string. For example WordDelimiterFilter splitting text:pdp-11
|
||
will cause the parser to generate text:"pdp 11" rather than (text:PDP OR text:11).
|
||
Note that autoGeneratePhraseQueries="true" tends to not work well for non whitespace
|
||
delimited languages. (yonik)
|
||
|
||
* SOLR-1925: Add CSVResponseWriter (use wt=csv) that returns the list of documents
|
||
in CSV format. (Chris Mattmann, yonik)
|
||
|
||
* SOLR-1240: "Range Faceting" has been added. This is a generalization
|
||
of the existing "Date Faceting" logic so that it now supports any
|
||
all stock numeric field types that support range queries in addition
|
||
to dates. facet.date is now deprecated in favor of this generalized mechanism.
|
||
(Gijs Kunze, hossman)
|
||
|
||
* SOLR-2021: Add SolrEncoder plugin to Highlighter. (koji)
|
||
|
||
* SOLR-2030: Make FastVectorHighlighter use of SolrEncoder. (koji)
|
||
|
||
* SOLR-2053: Add support for custom comparators in Solr spellchecker, per LUCENE-2479 (gsingers)
|
||
|
||
* SOLR-2049: Add hl.multiValuedSeparatorChar for FastVectorHighlighter, per LUCENE-2603. (koji)
|
||
|
||
* SOLR-2059: Add "types" attribute to WordDelimiterFilterFactory, which
|
||
allows you to customize how WordDelimiterFilter tokenizes text with
|
||
a configuration file. (Peter Karich, rmuir)
|
||
|
||
* SOLR-2099: Add ability to throttle rsync based replication using rsync option --bwlimit.
|
||
(Brandon Evans via koji)
|
||
|
||
* SOLR-1316: Create autosuggest component.
|
||
(Ankul Garg, Jason Rutherglen, Shalin Shekhar Mangar, Grant Ingersoll, Robert Muir, ab)
|
||
|
||
* SOLR-1568: Added "native" filtering support for PointType, GeohashField. Added LatLonType with filtering support too. See
|
||
http://wiki.apache.org/solr/SpatialSearch and the example. Refactored some items in Lucene spatial.
|
||
Removed SpatialTileField as the underlying CartesianTier is broken beyond repair and is going to be moved. (gsingers)
|
||
|
||
* SOLR-2128: Full parameter substitution for function queries.
|
||
Example: q=add($v1,$v2)&v1=mul(popularity,5)&v2=20.0
|
||
(yonik)
|
||
|
||
* SOLR-2133: Function query parser can now parse multiple comma separated
|
||
value sources. It also now fails if there is extra unexpected text
|
||
after parsing the functions, instead of silently ignoring it.
|
||
This allows expressions like q=dist(2,vector(1,2),$pt)&pt=3,4 (yonik)
|
||
|
||
* SOLR-2157: Suggester should return alpha-sorted results when onlyMorePopular=false (ab)
|
||
|
||
* SOLR-2010: Added ability to verify that spell checking collations have
|
||
actual results in the index. (James Dyer via gsingers)
|
||
|
||
* SOLR-2188: Added "maxTokenLength" argument to the factories for ClassicTokenizer,
|
||
StandardTokenizer, and UAX29URLEmailTokenizer. (Steven Rowe)
|
||
|
||
* SOLR-2129: Added a Solr module for dynamic metadata extraction/indexing with Apache UIMA.
|
||
See contrib/uima/README.txt for more information. (Tommaso Teofili via rmuir)
|
||
|
||
* SOLR-2325: Allow tagging and exclusion of main query for faceting. (yonik)
|
||
|
||
* SOLR-2263: Add ability for RawResponseWriter to stream binary files as well as
|
||
text files. (Eric Pugh via yonik)
|
||
|
||
* SOLR-860: Add debug output for MoreLikeThis. (koji)
|
||
|
||
* SOLR-1057: Add PathHierarchyTokenizerFactory. (ryan, koji)
|
||
|
||
Optimizations
|
||
----------------------
|
||
|
||
* SOLR-1679: Don't build up string messages in SolrCore.execute unless they
|
||
are necessary for the current log level.
|
||
(Fuad Efendi and hossman)
|
||
|
||
* SOLR-1874: Optimize PatternReplaceFilter for better performance. (rmuir, uschindler)
|
||
|
||
* SOLR-1968: speed up initial filter cache population for facet.method=enum and
|
||
also big terms for multi-valued facet.method=fc. The resulting speedup
|
||
for the first facet request is anywhere from 30% to 32x, depending on how many
|
||
terms are in the field and how many documents match per term. (yonik)
|
||
|
||
* SOLR-2089: Speed up UnInvertedField faceting (facet.method=fc for
|
||
multi-valued fields) when facet.limit is both high, and a high enough
|
||
percentage of the number of unique terms in the field. Extreme cases
|
||
yield speedups over 3x. (yonik)
|
||
|
||
* SOLR-2046: add common functions to scripts-util. (koji)
|
||
|
||
Bug Fixes
|
||
----------------------
|
||
* SOLR-1769: Solr 1.4 Replication - Repeater throwing NullPointerException (Jörgen Rydenius via noble)
|
||
|
||
* SOLR-1432: Make the new ValueSource.getValues(context,reader) delegate
|
||
to the original ValueSource.getValues(reader) so custom sources
|
||
will work. (yonik)
|
||
|
||
* SOLR-1572: FastLRUCache correctly implemented the LRU policy only
|
||
for the first 2B accesses. (yonik)
|
||
|
||
* SOLR-1582: copyField was ignored for BinaryField types (gsingers)
|
||
|
||
* SOLR-1563: Binary fields, including trie-based numeric fields, caused null
|
||
pointer exceptions in the luke request handler. (yonik)
|
||
|
||
* SOLR-1577: The example solrconfig.xml defaulted to a solr data dir
|
||
relative to the current working directory, even if a different solr home
|
||
was being used. The new behavior changes the default to a zero length
|
||
string, which is treated the same as if no dataDir had been specified,
|
||
hence the "data" directory under the solr home will be used. (yonik)
|
||
|
||
* SOLR-1584: SolrJ - SolrQuery.setIncludeScore() incorrectly added
|
||
fl=score to the parameter list instead of appending score to the
|
||
existing field list. (yonik)
|
||
|
||
* SOLR-1580: Solr Configuration ignores 'mergeFactor' parameter, always
|
||
uses Lucene default. (Lance Norskog via Mark Miller)
|
||
|
||
* SOLR-1593: ReverseWildcardFilter didn't work for surrogate pairs
|
||
(i.e. code points outside of the BMP), resulting in incorrect
|
||
matching. This change requires reindexing for any content with
|
||
such characters. (Robert Muir, yonik)
|
||
|
||
* SOLR-1596: A rollback operation followed by the shutdown of Solr
|
||
or the close of a core resulted in a warning:
|
||
"SEVERE: SolrIndexWriter was not closed prior to finalize()" although
|
||
there were no other consequences. (yonik)
|
||
|
||
* SOLR-1595: StreamingUpdateSolrServer used the platform default character
|
||
set when streaming updates, rather than using UTF-8 as the HTTP headers
|
||
indicated, leading to an encoding mismatch. (hossman, yonik)
|
||
|
||
* SOLR-1587: A distributed search request with fl=score, didn't match
|
||
the behavior of a non-distributed request since it only returned
|
||
the id,score fields instead of all fields in addition to score. (yonik)
|
||
|
||
* SOLR-1601: Schema browser does not indicate presence of charFilter. (koji)
|
||
|
||
* SOLR-1615: Backslash escaping did not work in quoted strings
|
||
for local param arguments. (Wojtek Piaseczny, yonik)
|
||
|
||
* SOLR-1628: log contains incorrect number of adds and deletes.
|
||
(Thijs Vonk via yonik)
|
||
|
||
* SOLR-343: Date faceting now respects facet.mincount limiting
|
||
(Uri Boness, Raiko Eckstein via hossman)
|
||
|
||
* SOLR-1624: Highlighter only highlights values from the first field value
|
||
in a multivalued field when term positions (term vectors) are stored.
|
||
(Chris Harris via yonik)
|
||
|
||
* SOLR-1635: Fixed error message when numeric values can't be parsed by
|
||
DOMUtils - notably for plugin init params in solrconfig.xml.
|
||
(hossman)
|
||
|
||
* SOLR-1651: Fixed Incorrect dataimport handler package name in SolrResourceLoader
|
||
(Akshay Ukey via shalin)
|
||
|
||
* SOLR-1660: CapitalizationFilter crashes if you use the maxWordCountOption
|
||
(Robert Muir via shalin)
|
||
|
||
* SOLR-1667: PatternTokenizer does not reset attributes such as positionIncrementGap
|
||
(Robert Muir via shalin)
|
||
|
||
* SOLR-1711: SolrJ - StreamingUpdateSolrServer had a race condition that
|
||
could halt the streaming of documents. The original patch to fix this
|
||
(never officially released) introduced another hanging bug due to
|
||
connections not being released.
|
||
(Attila Babo, Erik Hetzner, Johannes Tuchscherer via yonik)
|
||
|
||
* SOLR-1748, SOLR-1747, SOLR-1746, SOLR-1745, SOLR-1744: Streams and Readers
|
||
retrieved from ContentStreams are not closed in various places, resulting
|
||
in file descriptor leaks.
|
||
(Christoff Brill, Mark Miller)
|
||
|
||
* SOLR-1753: StatsComponent throws NPE when getting statistics for facets in distributed search
|
||
(Janne Majaranta via koji)
|
||
|
||
* SOLR-1736:In the slave , If 'mov'ing file does not succeed , copy the file (noble)
|
||
|
||
* SOLR-1579: Fixes to XML escaping in stats.jsp
|
||
(David Bowen and hossman)
|
||
|
||
* SOLR-1777: fieldTypes with sortMissingLast=true or sortMissingFirst=true can
|
||
result in incorrectly sorted results. (yonik)
|
||
|
||
* SOLR-1798: Small memory leak (~100 bytes) in fastLRUCache for every
|
||
commit. (yonik)
|
||

|
||
leaks in ResourceLoader. (yonik)
|
||
|
||
* SOLR-1850: change KeepWordFilter so a new word set is not created for
|
||
each instance (John Wang via yonik)
|
||
|
||
* SOLR-1706: fixed WordDelimiterFilter for certain combinations of options
|
||
where it would output incorrect tokens. (Robert Muir, Chris Male)
|
||
|
||
* SOLR-1936: The JSON response format needed to escape unicode code point
|
||
U+2028 - 'LINE SEPARATOR' (Robert Hofstra, yonik)
|
||
|
||
* SOLR-1914: Change the JSON response format to output float/double
|
||
values of NaN,Infinity,-Infinity as strings. (yonik)
|
||
|
||
* SOLR-1948: PatternTokenizerFactory should use parent's args (koji)
|
||
|
||
* SOLR-1870: Indexing documents using the 'javabin' format no longer
|
||
fails with a ClassCastException whenSolrInputDocuments contain field
|
||
values which are Collections or other classes that implement
|
||
Iterable. (noble, hossman)
|
||
|
||
* SOLR-1981: Solr will now fail correctly if solr.xml attempts to
|
||
specify multiple cores that have the same name (hossman)
|
||
|
||
* SOLR-1791: Fix messed up core names on admin gui (yonik via koji)
|
||
|
||
* SOLR-1995: Change date format from "hour in am/pm" to "hour in day"
|
||
in CoreContainer and SnapShooter. (Hayato Ito, koji)
|
||
|
||
* SOLR-2008: avoid possible RejectedExecutionException w/autoCommit
|
||
by making SolreCore close the UpdateHandler before closing the
|
||
SearchExecutor. (NarasimhaRaju, hossman)
|
||
|
||
* SOLR-2036: Avoid expensive fieldCache ram estimation for the
|
||
admin stats page. (yonik)
|
||
|
||
* SOLR-2047: ReplicationHandler should accept bool type for enable flag. (koji)
|
||
|
||
* SOLR-1630: Fix spell checking collation issue related to token positions (rmuir, gsingers)
|
||
|
||
* SOLR-2100: The replication handler backup command didn't save the commit
|
||
point and hence could fail when a newer commit caused the older commit point
|
||
to be removed before it was finished being copied. This did not affect
|
||
normal master/slave replication. (Peter Sturge via yonik)
|
||
|
||
* SOLR-2114: Fixed parsing error in hsin function. The function signature has changed slightly. (gsingers)
|
||
|
||
* SOLR-2083: SpellCheckComponent misreports suggestions when distributed (James Dyer via gsingers)
|
||
|
||
* SOLR-2111: Change exception handling in distributed faceting to work more
|
||
like non-distributed faceting, change facet_counts/exception from a String
|
||
to a List<String> to enable listing all exceptions that happened, and
|
||
prevent an exception in one facet command from affecting another
|
||
facet command. (yonik)
|
||
|
||
* SOLR-2110: Remove the restriction on names for local params
|
||
substitution/dereferencing. Properly encode local params in
|
||
distributed faceting. (yonik)
|
||
|
||
* SOLR-2135: Fix behavior of ConcurrentLRUCache when asking for
|
||
getLatestAccessedItems(0) or getOldestAccessedItems(0).

||
(David Smiley via hossman)
|
||
|
||
* SOLR-2148: Highlighter doesn't support q.alt. (koji)
|
||
|
||
* SOLR-2180: It was possible for EmbeddedSolrServer to leave searchers
|
||
open if a request threw an exception. (yonik)
|
||
|
||
* SOLR-2173: Suggester should always rebuild Lookup data if Lookup.load fails. (ab)
|
||
|
||
* SOLR-2081: BaseResponseWriter.isStreamingDocs causes
|
||
SingleResponseWriter.end to be called 2x
|
||
(Chris A. Mattmann via hossman)
|
||
|
||
* SOLR-2219: The init() method of every SolrRequestHandler was being
|
||
called twice. (ambikeshwar singh and hossman)
|
||
|
||
* SOLR-2285: duplicate SolrEventListeners no longer created (hossman)
|
||
|
||
* SOLR-1993: fix String cast assumption in JavaBinCodec - specific
|
||
addresses "commitWithin" option on Update requests.
|
||
(noble, hossman, and Maxim Valyanskiy)
|
||
|
||
* SOLR-2261: fix velocity template layout.vm that referred to an older
|
||
version of jquery. (Eric Pugh via rmuir)
|
||
|
||
* SOLR-2307: fix bug in PHPSerializedResponseWriter (wt=phps) when
|
||
dealing with SolrDocumentList objects -- ie: sharded queries.
|
||
(Antonio Verni via hossman)
|
||
|
||
* SOLR-2127: Fixed serialization of default core and indentation of solr.xml when serializing.
|
||
(Ephraim Ofir, Mark Miller)
|
||
|
||
* SOLR-2320: Fixed ReplicationHandler detail reporting for masters
|
||
(hossman)
|
||
|
||
* SOLR-482: Provide more exception handling in CSVLoader (gsingers)
|
||
|
||
* SOLR-1283: HTMLStripCharFilter sometimes threw a "Mark Invalid" exception.
|
||
(Julien Coloos, hossman, yonik)
|
||
|
||
* SOLR-2085: Improve SolrJ behavior when FacetComponent comes before
|
||
QueryComponent (Tomas Salfischberger via hossman)
|
||
|
||
* SOLR-1940: Fix SolrDispatchFilter behavior when Content-Type is
|
||
unknown (Lance Norskog and hossman)
|
||
|
||
* SOLR-1983: snappuller fails when modifiedConfFiles is not empty and
|
||
full copy of index is needed. (Alexander Kanarsky via yonik)
|
||
|
||
* SOLR-2156: SnapPuller fails to clean Old Index Directories on Full Copy
|
||
(Jayendra Patil via yonik)
|
||
|
||
* SOLR-96: Fix XML parsing in XMLUpdateRequestHandler and
|
||
DocumentAnalysisRequestHandler to respect charset from XML file and only
|
||
use HTTP header's "Content-Type" as a "hint". (uschindler)
|
||
|
||
* SOLR-2339: Fix sorting to explicitly generate an error if you
|
||
attempt to sort on a multiValued field. (hossman)
|
||
|
||
* SOLR-2348: Fix field types to explicitly generate an error if you
|
||
attempt to get a ValueSource for a multiValued field. (hossman)
|
||
|
||
* SOLR-2380: Distributed faceting could miss values when facet.sort=index
|
||
and when facet.offset was greater than 0. (yonik)
|
||
|
||
* SOLR-1656: XIncludes and other HREFs in XML files loaded by ResourceLoader
|
||
are fixed to be resolved using the URI standard (RFC 2396). The system
|
||
identifier is no longer a plain filename with path, it gets initialized
|
||
using a custom URI scheme "solrres:". This scheme is resolved using a
|
||
EntityResolver that utilizes ResourceLoader
|
||
(org.apache.solr.common.util.SystemIdResolver). This makes all relative
|
||
pathes in Solr's config files behave like expected. This change
|
||
introduces some backwards breaks in the API: Some config classes
|
||
(Config, SolrConfig, IndexSchema) were changed to take
|
||
org.xml.sax.InputSource instead of InputStream. There may also be some
|
||
backwards breaks in existing config files, it is recommended to check
|
||
your config files / XSLTs and replace all XIncludes/HREFs that were
|
||
hacked to use absolute paths to use relative ones. (uschindler)
|
||
|
||
* SOLR-309: Fix FieldType so setting an analyzer on a FieldType that
|
||
doesn't expect it will generate an error. Practically speaking this
|
||
means that Solr will now correctly generate an error on
|
||
initialization if the schema.xml contains an analyzer configuration
|
||
for a fieldType that does not use TextField. (hossman)
|
||
|
||
* SOLR-2192: StreamingUpdateSolrServer.blockUntilFinished was not
|
||
thread safe and could throw an exception. (yonik)
|
||
|
||
Other Changes
|
||
----------------------
|
||
|
||
* SOLR-1602: Refactor SOLR package structure to include o.a.solr.response
|
||
and move QueryResponseWriters in there
|
||
(Chris A. Mattmann, ryan, hoss)
|
||
|
||
* SOLR-1516: Addition of an abstract BaseResponseWriter class to simplify the
|
||
development of QueryResponseWriter implementations.
|
||
(Chris A. Mattmann via noble)
|
||
|
||
* SOLR-1592: Refactor XMLWriter startTag to allow arbitrary attributes to be written
|
||
(Chris A. Mattmann via noble)
|
||
|
||
* SOLR-1561: Added Lucene 2.9.1 spatial contrib jar to lib. (gsingers)
|
||
|
||
* SOLR-1570: Log warnings if uniqueKey is multi-valued or not stored (hossman, shalin)
|
||
|
||
* SOLR-1558: QueryElevationComponent only works if the uniqueKey field is
|
||
implemented using StrField. In previous versions of Solr no warning or
|
||
error would be generated if you attempted to use QueryElevationComponent,
|
||
it would just fail in unexpected ways. This has been changed so that it
|
||
will fail with a clear error message on initialization. (hossman)
|
||
|
||
* SOLR-1611: Added Lucene 2.9.1 collation contrib jar to lib (shalin)
|
||
|

|
||
(Robert Muir via Mark Miller)
|
||
|
||
* SOLR-1661: Remove adminCore from CoreContainer . removed deprecated methods setAdminCore(), getAdminCore() (noble)
|
||
|
||
* SOLR-1704: Google collections moved from clustering to core (noble)
|
||
|
||
* SOLR-1268: Add Lucene 2.9-dev r888785 FastVectorHighlighter contrib jar to lib. (koji)
|
||
|
||
* SOLR-1538: Reordering of object allocations in ConcurrentLRUCache to eliminate
|
||
(an extremely small) potential for deadlock.
|
||
(gabriele renzi via hossman)
|
||
|
||
* SOLR-1588: Removed some very old dead code.
|
||
(Chris A. Mattmann via hossman)
|
||
|
||
* SOLR-1696 : Deprecate old <highlighting> syntax and move configuration to HighlightComponent (noble)
|
||
|
||

|
||
for a function query (hossman)
|
||
|
||
* SOLR-1695: Improved error messages when adding a document that does not
|
||
contain exactly one value for the uniqueKey field (hossman)
|
||
|
||
* SOLR-1776: DismaxQParser and ExtendedDismaxQParser now use the schema.xml
|
||
"defaultSearchField" as the default value for the "qf" param instead of failing
|
||
with an error when "qf" is not specified. (hossman)
|
||
|
||
* SOLR-1851: luceneAutoCommit no longer has any effect - it has been remove (Mark Miller)
|
||
|
||
* SOLR-1865: SolrResourceLoader.getLines ignores Byte Order Markers (BOMs) at the
|
||
beginning of input files, these are often created by editors such as Windows
|
||
Notepad. (rmuir, hossman)
|
||
|
||
* SOLR-1938: ElisionFilterFactory will use a default set of French contractions
|
||
if you do not supply a custom articles file. (rmuir)
|
||
|
||
* SOLR-2003: SolrResourceLoader will report any encoding errors, rather than
|
||
silently using replacement characters for invalid inputs (blargy via rmuir)
|
||
|
||
* SOLR-1804: Google collections updated to Google Guava (which is a superset of collections and contains bug fixes) (gsingers)
|
||
|
||
* SOLR-2034: Switch to JavaBin codec version 2. Strings are now serialized
|
||
as the number of UTF-8 bytes, followed by the bytes in UTF-8. Previously
|
||
Strings were serialized as the number of UTF-16 chars, followed by the
|
||
bytes in Modified UTF-8. (hossman, yonik, rmuir)
|
||
|
||
* SOLR-2013: Add mapping-FoldToASCII.txt to example conf directory.
|
||
(Steven Rowe via koji)
|
||
|
||
* SOLR-2213: Upgrade to jQuery 1.4.3 (Erick Erickson via ryan)
|
||
|
||
* SOLR-1826: Add unit tests for highlighting with termOffsets=true
|
||
and overlapping tokens. (Stefan Oestreicher via rmuir)
|
||
|
||
* SOLR-2340: Add version infos to message in JavaBinCodec when throwing
|
||
exception. (koji)
|
||
|
||
* SOLR-2350: Since Solr no longer requires XML files to be in UTF-8
|
||
(see SOLR-96) SimplePostTool (aka: post.jar) has been improved to
|
||
work with files of any mime-type or charset. (hossman)
|
||
|
||
* SOLR-2365: Move DIH jars out of solr.war (David Smiley via yonik)
|
||
|
||
* SOLR-2381: Include a patched version of Jetty (6.1.26 + JETTY-1340)
|
||
to fix problematic UTF-8 handling for supplementary characters.
|
||
(Bernd Fehling, uschindler, yonik, rmuir)
|
||
|
||
* SOLR-2391: The preferred Content-Type for XML was changed to
|
||
application/xml. XMLResponseWriter now only delivers using this
|
||
type; updating documents and analyzing documents is still supported
|
||
using text/xml as Content-Type, too. If you have clients that are
|
||
hardcoded on text/xml as Content-Type, you have to change them.
|
||
(uschindler, rmuir)
|
||
|
||
* SOLR-2414: All ResponseWriters now use only ServletOutputStreams
|
||
and wrap their own Writer around it when serializing. This fixes
|
||
the bug in PHPSerializedResponseWriter that produced wrong string
|
||
length if the servlet container had a broken UTF-8 encoding that was
|
||
in fact CESU-8 (see SOLR-1091). The system property to enable the
|
||
CESU-8 byte counting in PHPSerializesResponseWriters for broken
|
||
servlet containers was therefore removed and is now ignored if set.
|
||
Output is always UTF-8. (uschindler, yonik, rmuir)
|
||
|
||
* SOLR-141: Errors and Exceptions are formated by ResponseWriter.
|
||
(Mike Sokolov, Rich Cariens, Daniel Naber, ryan)

||
----------------------
|
||
|
||
* SOLR-1522: Automated release signing process. (gsingers)
|
||
|
||
* SOLR-1891: Make lucene-jars-to-solr fail if copying any of the jars fails, and
|
||
update clean to remove the jars in that directory (Mark Miller)
|
||
|
||
* LUCENE-2466: Commons-Codec was upgraded from 1.3 to 1.4. (rmuir)
|
||
|
||
* SOLR-2042: Fixed some Maven deps (Drew Farris via gsingers)
|
||
|
||
* LUCENE-2657: Switch from using Maven POM templates to full POMs when
|
||
generating Maven artifacts (Steven Rowe)
|

||
================== Release 1.4.0 ==================
|
||
Release Date: See http://lucene.apache.org/solr for the official release date.
|
||
|
||
Upgrading from Solr 1.3
|
||
-----------------------
|
||
|
||
There is a new default faceting algorithm for multiVaued fields that should be
|
||
faster for most cases. One can revert to the previous algorithm (which has
|
||
also been improved somewhat) by adding facet.method=enum to the request.
|
||
|
||
Searching and sorting is now done on a per-segment basis, meaning that
|
||
the FieldCache entries used for sorting and for function queries are
|
||
created and used per-segment and can be reused for segments that don't
|
||
change between index updates. While generally beneficial, this can lead
|
||
to increased memory usage over 1.3 in certain scenarios:
|
||
1) A single valued field that was used for both sorting and faceting
|
||
in 1.3 would have used the same top level FieldCache entry. In 1.4,
|
||
sorting will use entries at the segment level while faceting will still
|
||
use entries at the top reader level, leading to increased memory usage.
|
||
2) Certain function queries such as ord() and rord() require a top level
|
||
FieldCache instance and can thus lead to increased memory usage. Consider
|
||
replacing ord() and rord() with alternatives, such as function queries
|
||
based on ms() for date boosting.
|
||
|
||
If you use custom Tokenizer or TokenFilter components in a chain specified in
|
||
schema.xml, they must support reusability. If your Tokenizer or TokenFilter
|
||
maintains state, it should implement reset(). If your TokenFilteFactory does
|
||
not return a subclass of TokenFilter, then it should implement reset() and call
|
||
reset() on it's input TokenStream. TokenizerFactory implementations must
|
||
now return a Tokenizer rather than a TokenStream.
|
||
|
||
New users of Solr 1.4 will have omitTermFreqAndPositions enabled for non-text
|
||
indexed fields by default, which avoids indexing term frequency, positions, and
|
||
payloads, making the index smaller and faster. If you are upgrading from an
|
||
earlier Solr release and want to enable omitTermFreqAndPositions by default,
|
||
change the schema version from 1.1 to 1.2 in schema.xml. Remove any existing
|
||
index and restart Solr to ensure that omitTermFreqAndPositions completely takes
|
||
affect.
|
||
|
||
The default QParserPlugin used by the QueryComponent for parsing the "q" param
|
||
has been changed, to remove support for the deprecated use of ";" as a separator
|
||
between the query string and the sort options when no "sort" param was used.
|
||
Users who wish to continue using the semi-colon based method of specifying the
|
||
sort options should explicitly set the defType param to "lucenePlusSort" on all
|
||
requests. (The simplest way to do this is by specifying it as a default param
|
||
for your request handlers in solrconfig.xml, see the example solrconfig.xml for
|
||
sample syntax.)
|
||
|
||
If spellcheck.extendedResults=true, the response format for suggestions
|
||
has changed, see SOLR-1071.
|
||
|
||
Use of the "charset" option when configuring the following Analysis
|
||
Factories has been deprecated and will cause a warning to be logged.
|
||
In future versions of Solr attempting to use this option will cause an
|
||
error. See SOLR-1410 for more information.

Versions of Major Components
|
||
----------------------------
|
||
Apache Lucene 2.9.1 (r832363 on 2.9 branch)
|
||
Apache Tika 0.4
|
||
Carrot2 3.1.0
|
||
|
||
Lucene Information
|
||
----------------
|
||
|
||
Since Solr is built on top of Lucene, many people add customizations to Solr
|
||
that are dependent on Lucene. Please see http://lucene.apache.org/java/2_9_0/,
|
||
especially http://lucene.apache.org/java/2_9_0/changes/Changes.html for more
|
||
information on the version of Lucene used in Solr.
|
||
|
||
Detailed Change List
|
||
----------------------
|
||
|
||
New Features
|
||
----------------------
|
||
1. SOLR-560: Use SLF4J logging API rather then JDK logging. The packaged .war file is
|
||
shipped with a JDK logging implementation, so logging configuration for the .war should
|
||
be identical to solr 1.3. However, if you are using the .jar file, you can select
|
||
which logging implementation to use by dropping a different binding.
|
||
See: http://www.slf4j.org/ (ryan)
|
||
|
||
2. SOLR-617: Allow configurable index deletion policy and provide a default implementation which
|
||
allows deletion of commit points on various criteria such as number of commits, age of commit
|
||
point and optimized status.
|
||
See http://lucene.apache.org/java/2_3_2/api/org/apache/lucene/index/IndexDeletionPolicy.html
|
||
(yonik, Noble Paul, Akshay Ukey via shalin)
|
||
|
||
3. SOLR-658: Allow Solr to load index from arbitrary directory in dataDir
|
||
(Noble Paul, Akshay Ukey via shalin)
|
||
|
||
4. SOLR-793: Add 'commitWithin' argument to the update add command. This behaves
|
||
similar to the global autoCommit maxTime argument except that it is set for
|
||
each request. (ryan)
|
||
|
||
5. SOLR-670: Add support for rollbacks in UpdateHandler. This allows user to rollback all changes
|
||
since the last commit. (Noble Paul, koji via shalin)
|
||
|
||
6. SOLR-813: Adding DoubleMetaphone Filter and Factory. Similar to the PhoneticFilter,
|
||
but this uses DoubleMetaphone specific calls (including alternate encoding)
|
||
(Todd Feak via ryan)
|
||
|
||
7. SOLR-680: Add StatsComponent. This gets simple statistics on matched numeric fields,
|
||
including: min, max, mean, median, stddev. (koji, ryan)
|
||
|
||
7.1 SOLR-1380: Added support for multi-valued fields (Harish Agarwal via gsingers)
|
||
|
||
8. SOLR-561: Added Replication implemented in Java as a request handler. Supports index replication
|
||
as well as configuration replication and exposes detailed statistics and progress information
|
||
on the Admin page. Works on all platforms. (Noble Paul, yonik, Akshay Ukey, shalin)
|
||
|
||
9. SOLR-746: Added "omitHeader" request parameter to omit the header from the response.
|
||
(Noble Paul via shalin)
|
||
|
||
10. SOLR-651: Added TermVectorComponent for serving up term vector information, plus IDF.
|
||
See http://wiki.apache.org/solr/TermVectorComponent (gsingers, Vaijanath N. Rao, Noble Paul)
|
||
|
||
12. SOLR-795: SpellCheckComponent supports building indices on optimize if configured in solrconfig.xml
|
||
(Jason Rennie, shalin)
|
||
|
||
13. SOLR-667: A LRU cache implementation based upon ConcurrentHashMap and other techniques to reduce
|
||
contention and synchronization overhead, to utilize multiple CPU cores more effectively.
|
||
(Fuad Efendi, Noble Paul, yonik via shalin)
|
||
|
||
14. SOLR-465: Add configurable DirectoryProvider so that alternate Directory
|
||
implementations can be specified via solrconfig.xml. The default

|
||
28. SOLR-906: Adding a StreamingUpdateSolrServer that writes update commands to
|

|
||
(Andrzej Bialecki, hossman, Mark Miller, John Wang)
|
||
|

||
65. SOLR-1237: firstSearcher and newSearcher can now be identified via the CommonParams.EVENT (evt) parameter
|
||
in a request. This allows a RequestHandler or SearchComponent to know when a newSearcher or firstSearcher
|
||
event happened. QuerySenderListender is the only implementation in Solr that implements this, but outside
|
||
implementations may wish to. See the AbstractSolrEventListener for a helper method. (gsingers)
|
||
|
||
66. SOLR-1343: Added HTMLStripCharFilter and marked HTMLStripReader, HTMLStripWhitespaceTokenizerFactory and

on OrdFieldSource#hashcode collisions. (Mark Miller)
|
||
|
||
49. SOLR-1207: equals method should compare this and other of DocList in DocSetBase (koji)
|
||
|
||
50. SOLR-1242: Human readable JVM info from system handler does integer cutoff rounding, even when dealing
|
||
with GB. Fixed to round to one decimal place. (Jay Hill, Mark Miller)
|
||
|
||
51. SOLR-1243: Admin RequestHandlers should not be cached over HTTP. (Mark Miller)
|
||
|
||
52. SOLR-1260: Fix implementations of set operations for DocList subclasses
|
||
and fix a bug in HashDocSet construction when offset != 0. These bugs
|
||
never manifested in normal Solr use and only potentially affect
|
||
custom code. (yonik)
|
||
|
||
53. SOLR-1171: Fix LukeRequestHandler so it doesn't rely on SolrQueryParser
|
||
and report incorrect stats when field names contain characters
|
||
SolrQueryParser considers special.
|
||
(hossman)
|
||
|
||
54. SOLR-1317: Fix CapitalizationFilterFactory to work when keep parameter is not specified.
|
||
(ehatcher)
|
||
|
||
55. SOLR-1342: CapitalizationFilterFactory uses incorrect term length calculations.
|
||
(Robert Muir via Mark Miller)
|
||
|
||
56. SOLR-1359: DoubleMetaphoneFilter didn't index original tokens if there was no
|
||
alternative, and could incorrectly skip or reorder tokens. (yonik)
|
||
|
||
57. SOLR-1360: Prevent PhoneticFilter from producing duplicate tokens. (yonik)
|
||
|
||
58. SOLR-1371: LukeRequestHandler/schema.jsp errored if schema had no
|
||
uniqueKey field. The new test for this also (hopefully) adds some
|
||
future proofing against similar bugs in the future. As a side
|
||
effect QueryElevationComponentTest was refactored, and a bug in
|
||
that test was found. (hossman)
|
||
|
||
59. SOLR-914: General finalize() improvements. No finalizer delegates
|
||
to the respective close/destroy method w/o first checking if it's
|
||
already been closed/destroyed; if it hasn't a, SEVERE error is
|
||
logged first. (noble, hossman)
|
||
|
||
60. SOLR-1362: WordDelimiterFilter had inconsistent behavior when setting
|
||
the position increment of tokens following a token consisting of all
|
||
delimiters, and could additionally lose big position increments.
|
||
(Robert Muir, yonik)
|
||
|
||
61. SOLR-1091: Jetty's use of CESU-8 for code points outside the BMP
|
||
resulted in invalid output from the serialized PHP writer. (yonik)
|
||
|
||
62. SOLR-1103: LukeRequestHandler (and schema.jsp) have been fixed to
|
||
include the "1" (ie: 2**0) bucket in the term histogram data.
|
||
(hossman)
|
||
|
||
63. SOLR-1398: Add offset corrections in PatternTokenizerFactory.
|
||
(Anders Melchiorsen, koji)
|
||
|
||
64. SOLR-1400: Properly handle zero-length tokens in TrimFilter. This
|
||
was not a bug in any released version. (Peter Wolanin, gsingers)
|
||
|
||
65. SOLR-1071: spellcheck.extendedResults returns an invalid JSON response
|
||
when count > 1. To fix, the extendedResults format was changed.
|
||
(Uri Boness, yonik)
|
||
|
||
66. SOLR-1381: Fixed improper handling of fields that have only term positions and not term offsets during Highlighting (Thorsten Fischer, gsingers)
|
||
|
||
67. SOLR-1427: Fixed registry.jsp issue with MBeans (gsingers)
|
||
|
||
68. SOLR-1468: SolrJ's XML response parsing threw an exception for null
|
||
names, such as those produced when facet.missing=true (yonik)
|
||
|
||
69. SOLR-1471: Fixed issue with calculating missing values for facets in single valued cases in Stats Component.
|
||
This is not correctly calculated for the multivalued case. (James Miller, gsingers)
|
||
|
||
70. SOLR-1481: Fixed omitHeader parameter for PHP ResponseWriter. (Jun Ohtani via billa)
|
||
|
||
71. SOLR-1448: Add weblogic.xml to solr webapp to enable correct operation in
|
||
WebLogic. (Ilan Rabinovitch via yonik)
|
||
|
||
72. SOLR-1504: empty char mapping can cause ArrayIndexOutOfBoundsException in analysis.jsp and co.
|
||
(koji)
|
||
|
||
73. SOLR-1394: HTMLStripCharFilter split tokens that contained entities and
|
||
often calculated offsets incorrectly for entities.
|
||
(Anders Melchiorsen via yonik)
|
||
|
||
74. SOLR-1517: Admin pages could stall waiting for localhost name resolution
|
||
if reverse DNS wasn't configured; this was changed so the DNS resolution
|
||
is attempted only once the first time an admin page is loaded.
|
||
(hossman)
|
||
|
||
75. SOLR-1529: More than 8 deleteByQuery commands in a single request
|
||
caused an error to be returned, although the deletes were
|
||
still executed. (asmodean via yonik)
|
||
|
||
Other Changes
|
||
----------------------
|
||
1. Upgraded to Lucene 2.4.0 (yonik)
|
||
|
||
2. SOLR-805: Upgraded to Lucene 2.9-dev (r707499) (koji)
|
||
|
||
3. DumpRequestHandler (/debug/dump): changed 'fieldName' to 'sourceInfo'. (ehatcher)
|
||
|
||
4. SOLR-852: Refactored common code in CSVRequestHandler and XMLUpdateRequestHandler (gsingers, ehatcher)
|
||
|
||
5. SOLR-871: Removed dependency on stax-utils.jar. If you using solr.jar and running
|
||
java 6, you can also remove woodstox and geronimo. (ryan)
|
||
|
||
6. SOLR-465: Upgraded to Lucene 2.9-dev (r719351) (shalin)
|
||
|
||
7. SOLR-889: Upgraded to commons-io-1.4.jar and commons-fileupload-1.2.1.jar (ryan)
|
||
|
||
8. SOLR-875: Upgraded to Lucene 2.9-dev (r723985) and consolidated the BitSet implementations (Michael Busch, gsingers)
|
||
|
||
9. SOLR-819: Upgraded to Lucene 2.9-dev (r724059) to get access to Arabic public constructors (gsingers)
|
||
and
|
||

|
||
in the solr-solrj.jar. (ryan)
|
||
|
||
11. SOLR-924: Code cleanup: make all existing finalize() methods call
|
||
super.finalize() in a finally block. All current instances extend
|
||
Object, so this doesn't fix any bugs, but helps protect against
|
||
future changes. (Kay Kay via hossman)
|
||
|
||
12. SOLR-885: NamedListCodec is renamed to JavaBinCodec and returns Object instead of NamedList.
|
||
(Noble Paul, yonik via shalin)
|
||
|
||
13. SOLR-84: Use new Solr logo in admin (Michiel via koji)
|
||

|
||
|
||

|
||
|

||
|
||
21. Upgraded to Lucene 2.9-dev r752164 (shalin)
|

|
||
|
||
24. Upgraded to Lucene 2.9-dev r764281 (shalin)

|
||
|
||

|
||
|
||
29. SOLR-997: Wait for a longer time for slave to complete replication in TestReplicationHandler
|
||
(Mark Miller via shalin)
|
||
|
||
30. SOLR-748: FacetComponent helper classes are made public as an experimental API.
|
||
(Wojtek Piaseczny via shalin)
|
||
|
||
31. Upgraded to Lucene 2.9-dev 773862 (Mark Miller)
|
||
|
||
32. Upgraded to Lucene 2.9-dev r776177 (shalin)
|
||
|
||
33. SOLR-1149: Made QParserPlugin and related classes extendible as an experimental API.

||
(Kaktu Chakarabati via shalin)
|
||
|
||

|
||
|
||
35. SOLR-786: Refactor DisMaxQParser to allow overriding certain features of DisMaxQParser
|
||
(Wojciech Biela via shalin)
|
||
|
||
36. SOLR-458: Add equals and hashCode methods to NamedList (Stefan Rinner, shalin)
|
||
|
||
37. SOLR-1184: Add option in solrconfig to open a new IndexReader rather than
|
||
using reopen. Done mainly as a fail-safe in the case that a user runs into
|
||
a reopen bug/issue. (Mark Miller)
|
||
|
||
38. SOLR-1215 use double quotes to enclose attributes in solr.xml (noble)
|
||
|
||
39. SOLR-1151: add dynamic copy field and maxChars example to example schema.xml.
|
||
(Peter Wolanin, Mark Miller)
|
||
|
||
40. SOLR-1233: remove /select?qt=/whatever restriction on /-prefixed request handlers.
|
||
(ehatcher)
|
||
|
||
41. SOLR-1257: logging.jsp has been removed and now passes through to the
|
||
hierarchical log level tool added in Solr 1.3. Users still
|
||
hitting "/admin/logging.jsp" should switch to "/admin/logging".
|
||
(hossman)
|
||
|
||
42. Upgraded to Lucene 2.9-dev r794238. Other changes include:
|
||
LUCENE-1614 - Use Lucene's DocIdSetIterator.NO_MORE_DOCS as the sentinel value.
|
||
LUCENE-1630 - Add acceptsDocsOutOfOrder method to Collector implementations.
|
||
LUCENE-1673, LUCENE-1701 - Trie has moved to Lucene core and renamed to NumericRangeQuery.
|
||
LUCENE-1662, LUCENE-1687 - Replace usage of ExtendedFieldCache by FieldCache.
|
||
(shalin)
|
||
|
||
42. SOLR-1241: Solr's CharFilter has been moved to Lucene. Remove CharFilter and related classes
|
||
from Solr and use Lucene's corresponding code (koji via shalin)
|
||
|
||
43. SOLR-1261: Lucene trunk renamed RangeQuery & Co to TermRangeQuery (Uwe Schindler via shalin)
|
||
|
||
44. Upgraded to Lucene 2.9-dev r801856 (Mark Miller)
|
||
|
||
45. SOLR1276: Added StatsComponentTest (Rafa<66>ł Ku<4B>ć, gsingers)
|
||
|
||
46. SOLR-1377: The TokenizerFactory API has changed to explicitly return a Tokenizer
|
||
rather then a TokenStream (that may be or may not be a Tokenizer). This change
|
||
is required to take advantage of the Token reuse improvements in lucene 2.9. (ryan)
|
||
|
||
47. SOLR-1410: Log a warning if the deprecated charset option is used
|
||
on GreekLowerCaseFilterFactory, RussianStemFilterFactory,
|
||
RussianLowerCaseFilterFactory or RussianLetterTokenizerFactory.
|
||
(Robert Muir via hossman)
|
||
|
||
48. SOLR-1423: Due to LUCENE-1906, Solr's tokenizer should use Tokenizer.correctOffset() instead of CharStream.correctOffset().
|
||
(Uwe Schindler via koji)
|
||
|
||
49. SOLR-1319, SOLR-1345: Upgrade Solr Highlighter classes to new Lucene Highlighter API. This upgrade has
|
||
resulted in a back compat break in the DefaultSolrHighlighter class - getQueryScorer is no longer
|
||
protected. If you happened to be overriding that method in custom code, overide getHighlighter instead.
|
||
Also, HighlightingUtils#getQueryScorer has been removed as it was deprecated and backcompat has been
|
||
broken with it anyway. (Mark Miller)
|
||
|
||
50. SOLR-1357 SolrInputDocument cannot process dynamic fields (Lars Grote via noble)
|
||
|
||
Build
|
||
----------------------
|
||
1. SOLR-776: Added in ability to sign artifacts via Ant for releases (gsingers)
|
||
|
||
2. SOLR-854: Added run-example target (Mark Miller via ehatcher)
|
||
|
||
3. SOLR-1054:Fix dist-src target for DataImportHandler (Ryuuichi Kumai via shalin)
|
||
|
||
4. SOLR-1219: Added proxy.setup target (koji)
|
||
|
||
5. SOLR-1386: In build.xml, use longfile="gnu" in tar task to avoid warnings about long file names
|
||
(Mark Miller via shalin)
|
||
|
||
6. SOLR-1441: Make it possible to run all tests in a package (shalin)
|
||
|
||
|
||
Documentation
|
||
----------------------
|
||
1. SOLR-789: The javadoc of RandomSortField is not readable (Nicolas Lalev<65>Á<EFBFBD>e via koji)
|
||
|
||
2. SOLR-962: Note about null handling in ModifiableSolrParams.add javadoc
|
||
(Kay Kay via hossman)
|
||
|
||
3. SOLR-1409: Added Solr Powered By Logos
|
||
|
||
================== Release 1.3.0 ==================
|
||
|
||
Upgrading from Solr 1.2
|
||
-----------------------
|
||
IMPORTANT UPGRADE NOTE: In a master/slave configuration, all searchers/slaves
|
||
should be upgraded before the master! If the master were to be updated
|
||
first, the older searchers would not be able to read the new index format.
|
||
|
||
The Porter snowball based stemmers in Lucene were updated (LUCENE-1142),
|
||
and are not guaranteed to be backward compatible at the index level
|
||
(the stem of certain words may have changed). Re-indexing is recommended.
|
||
|
||
Older Apache Solr installations can be upgraded by replacing
|
||
the relevant war file with the new version. No changes to configuration
|
||
files should be needed.
|
||
|
||
This version of Solr contains a new version of Lucene implementing
|
||
an updated index format. This version of Solr/Lucene can still read
|
||
and update indexes in the older formats, and will convert them to the new
|
||
format on the first index change. Be sure to backup your index before
|
||
upgrading in case you need to downgrade.
|
||
|
||
Solr now recognizes HTTP Request headers related to HTTP Caching (see
|
||
RFC 2616 sec13) and will by default respond with "304 Not Modified"
|
||
when appropriate. This should only affect users who access Solr via
|
||
an HTTP Cache, or via a Web-browser that has an internal cache, but if
|
||
you wish to suppress this behavior an '<httpCaching never304="true"/>'
|
||
option can be added to your solrconfig.xml. See the wiki (or the
|
||
example solrconfig.xml) for more details...
|
||
http://wiki.apache.org/solr/SolrConfigXml#HTTPCaching
|
||
|
||
In Solr 1.2, DateField did not enforce the canonical representation of
|
||
the ISO 8601 format when parsing incoming data, and did not generation
|
||
the canonical format when generating dates from "Date Math" strings
|
||
(particularly as it pertains to milliseconds ending in trailing zeros)
|
||
-- As a result equivalent dates could not always be compared properly.
|
||
This problem is corrected in Solr 1.3, but DateField users that might
|
||
have been affected by indexing inconsistent formats of equivilent
|
||
dates (ie: 1995-12-31T23:59:59Z vs 1995-12-31T23:59:59.000Z) may want
|
||
to consider reindexing to correct these inconsistencies. Users who
|
||
depend on some of the the "broken" behavior of DateField in Solr 1.2
|
||
(specificly: accepting any input that ends in a 'Z') should consider
|
||
using the LegacyDateField class as a possible alternative. Users that
|
||
desire 100% backwards compatibility should consider using the Solr 1.2
|
||
version of DateField.
|
||
|
||
Due to some changes in the lifecycle of TokenFilterFactories, users of
|
||
Solr 1.2 who have written Java code which constructs new instances of
|
||
StopFilterFactory, SynonymFilterFactory, or EnglishProterFilterFactory
|
||
will need to modify their code by adding a line like the following
|
||
prior to using the factory object...
|
||
factory.inform(SolrCore.getSolrCore().getSolrConfig().getResourceLoader());
|
||
These lifecycle changes do not affect people who use Solr "out of the
|
||
box" or who have developed their own TokenFilterFactory plugins. More
|
||
info can be found in SOLR-594.
|
||
|
||
The python client that used to ship with Solr is no longer included in
|
||
the distribution (see client/python/README.txt).
|
||
|
||
Detailed Change List
|
||
--------------------
|
||
|
||
New Features
|
||
1. SOLR-69: Adding MoreLikeThisHandler to search for similar documents using
|
||
lucene contrib/queries MoreLikeThis. MoreLikeThis is also available from
|
||
the StandardRequestHandler using ?mlt=true. (bdelacretaz, ryan)
|
||
|
||
2. SOLR-253: Adding KeepWordFilter and KeepWordFilterFactory. A TokenFilter
|
||
that keeps tokens with text in the registered keeplist. This behaves like
|
||
the inverse of StopFilter. (ryan)
|
||
|
||
3. SOLR-257: WordDelimiterFilter has a new parameter splitOnCaseChange,
|
||
which can be set to 0 to disable splitting "PowerShot" => "Power" "Shot".
|
||
(klaas)
|
||
|
||
4. SOLR-193: Adding SolrDocument and SolrInputDocument to represent documents
|
||
outside of the lucene Document infrastructure. This class will be used
|
||
by clients and for processing documents. (ryan)
|
||
|
||
5. SOLR-244: Added ModifiableSolrParams - a SolrParams implementation that
|
||
help you change values after initialization. (ryan)
|
||
|
||
6. SOLR-20: Added a java client interface with two implementations. One
|
||
implementation uses commons httpclient to connect to solr via HTTP. The
|
||
other connects to solr directly. Check client/java/solrj. This addition
|
||
also includes tests that start jetty and test a connection using the full
|
||
HTTP request cycle. (Darren Erik Vengroff, Will Johnson, ryan)
|
||
|
||
7. SOLR-133: Added StaxUpdateRequestHandler that uses StAX for XML parsing.
|
||
This implementation has much better error checking and lets you configure
|
||
a custom UpdateRequestProcessor that can selectively process update
|
||
requests depending on the request attributes. This class will likely
|
||
replace XmlUpdateRequestHandler. (Thorsten Scherler, ryan)
|
||
|
||
8. SOLR-264: Added RandomSortField, a utility field with a random sort order.
|
||
The seed is based on a hash of the field name, so a dynamic field
|
||
of this type is useful for generating different random sequences.
|
||
This field type should only be used for sorting or as a value source
|
||
in a FunctionQuery (ryan, hossman, yonik)
|
||
|
||
9. SOLR-266: Adding show=schema to LukeRequestHandler to show the parsed
|
||
schema fields and field types. (ryan)
|
||
|
||
10. SOLR-133: The UpdateRequestHandler now accepts multiple delete options
|
||
within a single request. For example, sending:
|
||
<delete><id>1</id><id>2</id></delete> will delete both 1 and 2. (ryan)
|
||
|
||
11. SOLR-269: Added UpdateRequestProcessor plugin framework. This provides
|
||
a reasonable place to process documents after they are parsed and
|
||
before they are committed to the index. This is a good place for custom
|
||
document manipulation or document based authorization. (yonik, ryan)
|
||
|
||
12. SOLR-260: Converting to a standard PluginLoader framework. This reworks
|
||
RequestHandlers, FieldTypes, and QueryResponseWriters to share the same
|
||
base code for loading and initializing plugins. This adds a new
|
||
configuration option to define the default RequestHandler and
|
||
QueryResponseWriter in XML using default="true". (ryan)
|
||
|
||
13. SOLR-225: Enable pluggable highlighting classes. Allow configurable
|
||
highlighting formatters and Fragmenters. (ryan)
|
||
|
||
14. SOLR-273/376/452/516: Added hl.maxAnalyzedChars highlighting parameter, defaulting
|
||
to 50k, hl.alternateField, which allows the specification of a backup
|
||
field to use as summary if no keywords are matched, and hl.mergeContiguous,
|
||
which combines fragments if they are adjacent in the source document.
|
||
(klaas, Grant Ingersoll, Koji Sekiguchi via klaas)
|
||
|
||
15. SOLR-291: Control maximum number of documents to cache for any entry
|
||
in the queryResultCache via queryResultMaxDocsCached solrconfig.xml
|
||
entry. (Koji Sekiguchi via yonik)
|
||
|
||
16. SOLR-240: New <lockType> configuration setting in <mainIndex> and
|
||
<indexDefaults> blocks supports all Lucene builtin LockFactories.
|
||
'single' is recommended setting, but 'simple' is default for total
|
||
backwards compatibility.
|
||
(Will Johnson via hossman)
|
||
|
||
17. SOLR-248: Added CapitalizationFilterFactory that creates tokens with
|
||
normalized capitalization. This filter is useful for facet display,
|
||
but will not work with a prefix query. (ryan)
|
||
SOLR-468: Change to the semantics to keep the original token, not the
|
||
token in the Map. Also switched to use Lucene's new reusable token
|
||
capabilities. (gsingers)
|
||
|
||
18. SOLR-307: Added NGramFilterFactory and EdgeNGramFilterFactory.
|
||
(Thomas Peuss via Otis Gospodnetic)
|
||
|
||
19. SOLR-305: analysis.jsp can be given a fieldtype instead of a field
|
||
name. (hossman)
|
||
|
||
20. SOLR-102: Added RegexFragmenter, which splits text for highlighting
|
||
based on a given pattern. (klaas)
|
||
|
||
21. SOLR-258: Date Faceting added to SimpleFacets. Facet counts
|
||
computed for ranges of size facet.date.gap (a DateMath expression)
|
||
between facet.date.start and facet.date.end. (hossman)
|
||
|
||
22. SOLR-196: A PHP serialized "phps" response writer that returns a
|
||
serialized array that can be used with the PHP function unserialize,
|
||
and a PHP response writer "php" that may be used by eval.
|
||
(Nick Jenkin, Paul Borgermans, Pieter Berkel via yonik)
|
||
|
||
23. SOLR-308: A new UUIDField class which accepts UUID string values,
|
||
as well as the special value of "NEW" which triggers generation of
|
||
a new random UUID.
|
||
(Thomas Peuss via hossman)
|
||
|
||
24. SOLR-349: New FunctionQuery functions: sum, product, div, pow, log,
|
||
sqrt, abs, scale, map. Constants may now be used as a value source.
|
||
(yonik)
|
||
|
||
25. SOLR-359: Add field type className to Luke response, and enabled access
|
||
to the detailed field information from the solrj client API.
|
||
(Grant Ingersoll via ehatcher)
|
||
|
||
26. SOLR-334: Pluggable query parsers. Allows specification of query
|
||
type and arguments as a prefix on a query string. (yonik)
|
||
|
||
27. SOLR-351: External Value Source. An external file may be used
|
||
to specify the values of a field, currently usable as
|
||
a ValueSource in a FunctionQuery. (yonik)
|
||
|
||
28. SOLR-395: Many new features for the spell checker implementation, including
|
||
an extended response mode with much richer output, multi-word spell checking,
|
||
and a bevy of new and renamed options (see the wiki).
|
||
(Mike Krimerman, Scott Taber via klaas).
|
||
|
||
29. SOLR-408: Added PingRequestHandler and deprecated SolrCore.getPingQueryRequest().
|
||
Ping requests should be configured using standard RequestHandler syntax in
|
||
solrconfig.xml rather then using the <pingQuery></pingQuery> syntax.
|
||
(Karsten Sperling via ryan)
|
||
|
||
30. SOLR-281: Added a 'Search Component' interface and converted StandardRequestHandler
|
||
and DisMaxRequestHandler to use this framework.
|
||
(Sharad Agarwal, Henri Biestro, yonik, ryan)
|
||
|
||
31. SOLR-176: Add detailed timing data to query response output. The SearchHandler
|
||
interface now returns how long each section takes. (klaas)
|
||
|
||
32. SOLR-414: Plugin initialization now supports SolrCore and ResourceLoader "Aware"
|
||
plugins. Plugins that implement SolrCoreAware or ResourceLoaderAware are
|
||
informed about the SolrCore/ResourceLoader. (Henri Biestro, ryan)
|
||
|
||
33. SOLR-350: Support multiple SolrCores running in the same solr instance and allows
|
||
runtime runtime management for any running SolrCore. If a solr.xml file exists
|
||
in solr.home, this file is used to instanciate multiple cores and enables runtime
|
||
core manipulation. For more informaion see: http://wiki.apache.org/solr/CoreAdmin
|
||
(Henri Biestro, ryan)
|
||
|
||
34. SOLR-447: Added an single request handler that will automatically register all
|
||
standard admin request handlers. This replaces the need to register (and maintain)
|
||
the set of admin request handlers. Assuming solrconfig.xml includes:
|
||
<requestHandler name="/admin/" class="org.apache.solr.handler.admin.AdminHandlers" />
|
||
This will register: Luke/SystemInfo/PluginInfo/ThreadDump/PropertiesRequestHandler.
|
||
(ryan)
|
||
|
||
35. SOLR-142: Added RawResponseWriter and ShowFileRequestHandler. This returns config
|
||
files directly. If AdminHandlers are configured, this will be added automatically.
|
||
The jsp files /admin/get-file.jsp and /admin/raw-schema.jsp have been deprecated.
|
||
The deprecated <admin><gettableFiles> will be automatically registered with
|
||
a ShowFileRequestHandler instance for backwards compatibility. (ryan)
|
||
|
||
36. SOLR-446: TextResponseWriter can write SolrDocuments and SolrDocumentLists the
|
||
same way it writes Document and DocList. (yonik, ryan)
|
||
|
||
37. SOLR-418: Adding a query elevation component. This is an optional component to
|
||
elevate some documents to the top positions (or exclude them) for a given query.
|
||
(ryan)
|
||
|
||
38. SOLR-478: Added ability to get back unique key information from the LukeRequestHandler.
|
||
(gsingers)
|
||
|
||
39. SOLR-127: HTTP Caching awareness. Solr now recognizes HTTP Request
|
||
headers related to HTTP Caching (see RFC 2616 sec13) and will respond
|
||
with "304 Not Modified" when appropriate. New options have been added
|
||
to solrconfig.xml to influence this behavior.
|
||
(Thomas Peuss via hossman)
|
||
|
||
40. SOLR-303: Distributed Search over HTTP. Specification of shards
|
||
argument causes Solr to query those shards and merge the results
|
||
into a single response. Querying, field faceting (sorted only),
|
||
query faceting, highlighting, and debug information are supported
|
||
in distributed mode.
|
||
(Sharad Agarwal, Patrick O'Leary, Sabyasachi Dalal, Stu Hood,
|
||
Jayson Minard, Lars Kotthoff, ryan, yonik)
|
||
|
||
41. SOLR-356: Pluggable functions (value sources) that allow
|
||
registration of new functions via solrconfig.xml
|
||
(Doug Daniels via yonik)
|
||
|
||
42. SOLR-494: Added cool admin Ajaxed schema explorer.
|
||
(Greg Ludington via ehatcher)
|
||
|
||
43. SOLR-497: Added date faceting to the QueryResponse in SolrJ
|
||
and QueryResponseTest (Shalin Shekhar Mangar via gsingers)
|
||
|
||
44. SOLR-486: Binary response format, faster and smaller
|
||
than XML and JSON response formats (use wt=javabin).
|
||
BinaryResponseParser for utilizing the binary format via SolrJ
|
||
and is now the default.
|
||
(Noble Paul, yonik)
|
||
|
||
45. SOLR-521: StopFilterFactory support for "enablePositionIncrements"
|
||
(Walter Ferrara via hossman)
|
||
|
||
46. SOLR-557: Added SolrCore.getSearchComponents() to return an unmodifiable Map. (gsingers)
|
||
|
||
47. SOLR-516: Added hl.maxAlternateFieldLength parameter, to set max length for hl.alternateField
|
||
(Koji Sekiguchi via klaas)
|
||
|
||
48. SOLR-319: Changed SynonymFilterFactory to "tokenize" synonyms file.
|
||
To use a tokenizer, specify "tokenizerFactory" attribute in <filter>.
|
||
For example:
|
||
<tokenizer class="solr.CJKTokenizerFactory"/>
|
||
<filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" expand="true"
|
||
ignoreCase="true" tokenizerFactory="solr.CJKTokenizerFactory"/>
|
||
(koji)
|
||
|
||
49. SOLR-515: Added SimilarityFactory capability to schema.xml,
|
||
making config file parameters usable in the construction of
|
||
the global Lucene Similarity implementation.
|
||
(ehatcher)
|
||
|
||
50. SOLR-536: Add a DocumentObjectBinder to solrj that converts Objects to and
|
||
from SolrDocuments. (Noble Paul via ryan)
|
||
|
||
51. SOLR-595: Add support for Field level boosting in the MoreLikeThis Handler.
|
||
(Tom Morton, gsingers)
|
||
|
||
52. SOLR-572: Added SpellCheckComponent and org.apache.solr.spelling package to support more spell
|
||
checking functionality. Also includes ability to add your own SolrSpellChecker implementation that
|
||
plugs in. See http://wiki.apache.org/solr/SpellCheckComponent for more details
|
||
(Shalin Shekhar Mangar, Bojan Smid, gsingers)
|
||
|
||
53. SOLR-679: Added accessor methods to Lucene based spell checkers (gsingers)
|
||
|
||
54. SOLR-423: Added Request Handler close hook notification so that RequestHandlers can be notified
|
||
when a core is closing. (gsingers, ryan)
|
||
|
||
55. SOLR-603: Added ability to partially optimize. (gsingers)
|
||
|
||
56. SOLR-483: Add byte/short sorting support (gsingers)
|
||
|
||
57. SOLR-14: Add preserveOriginal flag to WordDelimiterFilter
|
||
(Geoffrey Young, Trey Hyde, Ankur Madnani, yonik)
|
||
|
||
58. SOLR-502: Add search timeout support. (Sean Timm via yonik)
|
||
|
||
59. SOLR-605: Add the ability to register callbacks programatically (ryan, Noble Paul)
|
||
|
||
60. SOLR-610: hl.maxAnalyzedChars can be -1 to highlight everything (Lars Kotthoff via klaas)
|
||
|
||
61. SOLR-522: Make analysis.jsp show payloads. (Tricia Williams via yonik)
|
||
|
||
62. SOLR-611: Expose sort_values returned by QueryComponent in SolrJ's QueryResponse
|
||
(Dan Rosher via shalin)
|
||
|
||
63. SOLR-256: Support exposing Solr statistics through JMX (Sharad Agrawal, shalin)
|
||
|
||
64. SOLR-666: Expose warmup time in statistics for SolrIndexSearcher and LRUCache (shalin)
|
||
|
||
65. SOLR-663: Allow multiple files for stopwords, keepwords, protwords and synonyms
|
||
(Otis Gospodnetic, shalin)
|
||
|
||
66. SOLR-469: Added DataImportHandler as a contrib project which makes indexing data from Databases,
|
||
XML files and HTTP data sources into Solr quick and easy. Includes API and implementations for
|
||
supporting multiple data sources, processors and transformers for importing data. Supports full
|
||
data imports as well as incremental (delta) indexing. See http://wiki.apache.org/solr/DataImportHandler
|
||
for more details. (Noble Paul, shalin)
|
||
|
||
67. SOLR-622: SpellCheckComponent supports auto-loading indices on startup and optionally, (re)builds
|
||
indices on newSearcher event, if configured in solrconfig.xml (shalin)
|
||
|
||
68. SOLR-554: Hierarchical JDK log level selector for SOLR Admin replaces logging.jsp
|
||
(Sean Timm via shalin)
|
||
|
||
69. SOLR-506: Emitting HTTP Cache headers can be enabled or disabled through configuration on a
|
||
per-handler basis (shalin)
|
||
|
||
70. SOLR-716: Added support for properties in configuration files. Properties can be specified in
|
||
solr.xml and can be used in solrconfig.xml and schema.xml (Henri Biestro, hossman, ryan, shalin)
|
||
|
||
71. SOLR-1129 : Support binding dynamic fields to beans in SolrJ (Avlesh Singh , noble)
|
||
|
||
72. SOLR-920 : Cache and reuse IndexSchema . A new attribute added in solr.xml called 'shareSchema' (noble)
|
||
|
||
Changes in runtime behavior
|
||
1. SOLR-559: use Lucene updateDocument, deleteDocuments methods. This
|
||
removes the maxBufferedDeletes parameter added by SOLR-310 as Lucene
|
||
now manages the deletes. This provides slightly better indexing
|
||
performance and makes overwrites atomic, eliminating the possibility of
|
||
a crash causing duplicates. (yonik)
|
||
|
||
2. SOLR-689 / SOLR-695: If you have used "MultiCore" functionality in an unreleased
|
||
version of 1.3-dev, many classes and configs have been renamed for the official
|
||
1.3 release. Speciffically, solr.xml has replaced multicore.xml, and uses a slightly
|
||
different syntax. The solrj classes: MultiCore{Request/Response/Params} have been
|
||
renamed: CoreAdmin{Request/Response/Params} (hossman, ryan, Henri Biestro)
|
||
|
||
3. SOLR-647: reference count the SolrCore uses to prevent a premature
|
||
close while a core is still in use. (Henri Biestro, Noble Paul, yonik)
|
||
|
||
4. SOLR-737: SolrQueryParser now uses a ConstantScoreQuery for wildcard
|
||
queries that prevent an exception from being thrown when the number
|
||
of matching terms exceeds the BooleanQuery clause limit. (yonik)
|
||
|
||
Optimizations
|
||
1. SOLR-276: improve JSON writer speed. (yonik)
|
||
|
||
2. SOLR-310: bound and reduce memory usage by providing <maxBufferedDeletes> parameter,
|
||
which flushes deleted without forcing the user to use <commit/> for this purpose.
|
||
(klaas)
|
||
|
||
3. SOLR-348: short-circuit faceting if less than mincount docs match. (yonik)
|
||
|
||
4. SOLR-354: Optimize removing all documents. Now when a delete by query
|
||
of *:* is issued, the current index is removed. (yonik)
|
||
|
||
5. SOLR-377: Speed up response writers. (yonik)
|
||
|
||
6. SOLR-342: Added support into the SolrIndexWriter for using several new features of the new
|
||
LuceneIndexWriter, including: setRAMBufferSizeMB(), setMergePolicy(), setMergeScheduler.
|
||
Also, added support to specify Lucene's autoCommit functionality (not to be confused with Solr's
|
||
similarily named autoCommit functionality) via the <luceneAutoCommit> config. item. See the test
|
||
and example solrconfig.xml <indexDefaults> section for usage. Performance during indexing should
|
||
be significantly increased by moving up to 2.3 due to Lucene's new indexing capabilities.
|
||
Furthermore, the setRAMBufferSizeMB makes it more logical to decide on tuning factors related to
|
||
indexing. For best performance, leave the mergePolicy and mergeScheduler as the defaults and set
|
||
ramBufferSizeMB instead of maxBufferedDocs. The best value for this depends on the types of
|
||
documents in use. 32 should be a good starting point, but reports have shown up to 48 MB provides
|
||
good results. Note, it is acceptable to set both ramBufferSizeMB and maxBufferedDocs, and Lucene
|
||
will flush based on whichever limit is reached first. (gsingers)
|
||
|
||
7. SOLR-330: Converted TokenStreams to use Lucene's new char array based
|
||
capabilities. (gsingers)
|
||
|
||
8. SOLR-624: Only take snapshots if there are differences to the index (Richard Trey Hyde via gsingers)
|
||
|
||
9. SOLR-587: Delete by Query performance greatly improved by using
|
||
new underlying Lucene IndexWriter implementation. (yonik)
|
||
|
||
10. SOLR-730: Use read-only IndexReaders that don't synchronize
|
||
isDeleted(). This will speed up function queries and *:* queries
|
||
as well as improve their scalability on multi-CPU systems.
|
||
(Mark Miller via yonik)
|
||
|
||
Bug Fixes

|
||
(hossman)
|
||
|
||
7. SOLR-331: Fix WordDelimiterFilter handling of offsets for synonyms or
|
||
other injected tokens that can break highlighting. (yonik)
|
||
|
||
8. SOLR-282: Snapshooter does not work on Solaris and OS X since the cp command
|
||
there does not have the -l option. Also updated commit/optimize related
|
||
scripts to handle both old and new response format. (bill)
|
||
|
||
9. SOLR-294: Logging of elapsed time broken on Solaris because the date command
|
||
there does not support the %s output format. (bill)
|

can result in an out-of-memory exception, even for a small index. (yonik)
|
||
|
||
14. The CSV loader incorrectly threw an exception when given
|
||
header=true (the default). (ryan, yonik)
|
||
|
||
15. SOLR-449: the python and ruby response writers are now able to correctly
|
||
output NaN and Infinity in their respective languages. (klaas)
|
||
|
||
16. SOLR-42: HTMLStripReader tokenizers now preserve correct source
|
||
offsets for highlighting. (Grant Ingersoll via yonik)

18. SOLR-324: Add proper support for Long and Doubles in sorting, etc. (gsingers)
|
||
|
||
19. SOLR-496: Cache-Control max-age changed to Long so Expires
|
||
calculation won't cause overflow. (Thomas Peuss via hossman)
|
||
|
||
20. SOLR-535: Fixed typo (Tokenzied -> Tokenized) in schema.jsp (Thomas Peuss via billa)
|
||
|
||
21. SOLR-529: Better error messages from SolrQueryParser when field isn't
|

specified and there is no defaultSearchField in schema.xml
|
||
(Lars Kotthoff via hossman)
|
||
|
||
22. SOLR-530: Better error messages/warnings when parsing schema.xml:

||
|
||
23. SOLR-528: Better error message when defaultSearchField is bogus or not
|
||
indexed. (Lars Kotthoff via hossman)

|
||
(hossman)
|

||
25. SOLR-400: SolrExceptionTest should now handle using OpenDNS as a DNS provider (gsingers)
|
||
|
||

|
||
(hossman)
|

27. SOLR-267: Changed logging to report number of hits, and also provide a mechanism to add log
|
||
messages to be output by the SolrCore via a NamedList toLog member variable.

||
|
||
29. SOLR-470, SOLR-552, SOLR-544, SOLR-701: Multiple fixes to DateField
|
||
regarding lenient parsing of optional milliseconds, and correct
|
||
formating using the canonical representation. LegacyDateField has
|
||
been added for people who have come to depend on the existing
|
||
broken behavior. (hossman, Stefan Oestreicher)
|
||
|
||
30. SOLR-539: Fix for non-atomic long counters and a cast fix to avoid divide

|
||
(Hannes Schmidt via billa)
|
||
|
||
35. SOLR-597: SolrServlet no longer "caches" SolrCore. This was causing
|
||
problems in Resin, and could potentially cause problems for customized
|
||
usages of SolrServlet.
|
||
|
||
36. SOLR-585: Now sets the QParser on the ResponseBuilder (gsingers)
|

||
(Yousef Ourabi and hossman)
|
||
|
||
39. SOLR-443: SolrJ: Declare UTF-8 charset on POSTed parameters
|
||
to avoid problems with servlet containers that default to latin-1

||
and allow switching of the exact POST mechanism for parameters
|
||
via useMultiPartPost in CommonsHttpSolrServer.
|
||
(Lars Kotthoff, Andrew Schurman, ryan, yonik)
|
||
|
||
40. SOLR-556: multi-valued fields always highlighted in disparate snippets
|
||
(Lars Kotthoff via klaas)

|
||
containers such as Tomcat. (Hiroaki Kawai, Lars Kotthoff via yonik)
|
||
|
||
42. SOLR-616: SpellChecker accuracy configuration is not applied for FileBasedSpellChecker.
|
||
Apply it for FileBasedSpellChecker and IndexBasedSpellChecker both.
|
||
(shalin)
|
||
|
||
43. SOLR-648: SpellCheckComponent throws NullPointerException on using spellcheck.q request
|
||
parameter after restarting Solr, if reload is called but build is not called.
|
||
(Jonathan Lee, shalin)
|
||
|
||
44. SOLR-598: DebugComponent now always occurs last in the SearchHandler list unless the
|
||
components are explicitly declared. (gsingers)

|
||
|
||
50. SOLR-749: Allow QParser and ValueSourceParsers to be extended with same name (hossman, gsingers)
|
||
|
||
Other Changes
|
||
1. SOLR-135: Moved common classes to org.apache.solr.common and altered the
|
||
build scripts to make two jars: apache-solr-1.3.jar and
|
||
apache-solr-1.3-common.jar. This common.jar can be used in client code;
|
||
It does not have lucene or junit dependencies. The original classes
|
||
have been replaced with a @Deprecated extended class and are scheduled
|
||
to be removed in a later release. While this change does not affect API
|
||
compatibility, it is recommended to update references to these
|
||
deprecated classes. (ryan)

|
||
================== Release 1.2 ==================
|
||
|
||
Upgrading from Solr 1.1
|
||
-------------------------------------
|
||
IMPORTANT UPGRADE NOTE: In a master/slave configuration, all searchers/slaves
|
||
should be upgraded before the master! If the master were to be updated
|
||
first, the older searchers would not be able to read the new index format.
|
||
|
||
Older Apache Solr installations can be upgraded by replacing
|
||
the relevant war file with the new version. No changes to configuration
|
||
files should be needed.
|
||
|
||
This version of Solr contains a new version of Lucene implementing
|
||
an updated index format. This version of Solr/Lucene can still read
|
||
and update indexes in the older formats, and will convert them to the new
|
||
format on the first index change. One change in the new index format
|
||
is that all "norms" are kept in a single file, greatly reducing the number
|
||
of files per segment. Users of compound file indexes will want to consider
|
||
converting to the non-compound format for faster indexing and slightly better
|
||
search concurrency.
|
||
|
||
The JSON response format for facets has changed to make it easier for
|
||
clients to retain sorted order. Use json.nl=map explicitly in clients
|
||
to get the old behavior, or add it as a default to the request handler
|
||
in solrconfig.xml
|
||
|
||
The Lucene based Solr query syntax is slightly more strict.
|
||
A ':' in a field value must be escaped or the whole value must be quoted.
|
||
|
||
The Solr "Request Handler" framework has been updated in two key ways:
|
||
First, if a Request Handler is registered in solrconfig.xml with a name
|
||
starting with "/" then it can be accessed using path-based URL, instead of
|
||
using the legacy "/select?qt=name" URL structure. Second, the Request
|
||
Handler framework has been extended making it possible to write Request
|
||
Handlers that process streams of data for doing updates, and there is a
|
||
new-style Request Handler for XML updates given the name of "/update" in
|
||
the example solrconfig.xml. Existing installations without this "/update"
|
||
handler will continue to use the old update servlet and should see no
|
||
changes in behavior. For new-style update handlers, errors are now
|
||
reflected in the HTTP status code, Content-type checking is more strict,
|
||
and the response format has changed and is controllable via the wt
|
||
parameter.
|
||
|
||
|
||
|
||
Detailed Change List
|
||
--------------------
|
||
|
||
New Features
|
||
1. SOLR-82: Default field values can be specified in the schema.xml.
|
||
(Ryan McKinley via hossman)
|
||
|
||
2. SOLR-89: Two new TokenFilters with corresponding Factories...
|
||
* TrimFilter - Trims leading and trailing whitespace from Tokens
|
||
* PatternReplaceFilter - applies a Pattern to each token in the
|
||
stream, replacing match occurances with a specified replacement.
|
||
(hossman)
|
||
|
||
3. SOLR-91: allow configuration of a limit of the number of searchers
|
||
that can be warming in the background. This can be used to avoid
|
||
out-of-memory errors, or contention caused by more and more searchers
|
||
warming in the background. An error is thrown if the limit specified
|
||
by maxWarmingSearchers in solrconfig.xml is exceeded. (yonik)
|
||
|
||
4. SOLR-106: New faceting parameters that allow specification of a
|
||
minimum count for returned facets (facet.mincount), paging through facets
|
||
(facet.offset, facet.limit), and explicit sorting (facet.sort).
|
||
facet.zeros is now deprecated. (yonik)
|
||
|
||
5. SOLR-80: Negative queries are now allowed everywhere. Negative queries
|
||
are generated and cached as their positive counterpart, speeding
|
||
generation and generally resulting in smaller sets to cache.
|
||
Set intersections in SolrIndexSearcher are more efficient,
|
||
starting with the smallest positive set, subtracting all negative
|
||
sets, then intersecting with all other positive sets. (yonik)
|
||
|
||
6. SOLR-117: Limit a field faceting to constraints with a prefix specified
|
||
by facet.prefix or f.<field>.facet.prefix. (yonik)
|
||
|
||
7. SOLR-107: JAVA API: Change NamedList to use Java5 generics
|
||
and implement Iterable<Map.Entry> (Ryan McKinley via yonik)
|
||
|
||
8. SOLR-104: Support for "Update Plugins" -- RequestHandlers that want
|
||
access to streams of data for doing updates. ContentStreams can come
|
||
from the raw POST body, multi-part form data, or remote URLs.
|
||
Included in this change is a new SolrDispatchFilter that allows
|
||
RequestHandlers registered with names that begin with a "/" to be
|
||
accessed using a URL structure based on that name.
|
||
(Ryan McKinley via hossman)
|
||
|
||
9. SOLR-126: DirectUpdateHandler2 supports autocommitting after a specified time
|
||
(in ms), using <autoCommit><maxTime>10000</maxTime></autoCommit>.
|
||
(Ryan McKinley via klaas).
|
||
|
||
10. SOLR-116: IndexInfoRequestHandler added. (Erik Hatcher)
|
||
|
||
11. SOLR-79: Add system property ${<sys.prop>[:<default>]} substitution for
|
||
configuration files loaded, including schema.xml and solrconfig.xml.
|
||
(Erik Hatcher with inspiration from Andrew Saar)
|
||
|
||
12. SOLR-149: Changes to make Solr more easily embeddable, in addition
|
||
to logging which request handler handled each request.
|
||
(Ryan McKinley via yonik)
|
||
|
||
13. SOLR-86: Added standalone Java-based command-line updater.
|
||
(Erik Hatcher via Bertrand Delecretaz)
|
||
|
||
14. SOLR-152: DisMaxRequestHandler now supports configurable alternate
|
||
behavior when q is not specified. A "q.alt" param can be specified
|
||
using SolrQueryParser syntax as a mechanism for specifying what query
|
||
the dismax handler should execute if the main user query (q) is blank.
|
||
(Ryan McKinley via hossman)
|
||
|
||
15. SOLR-158: new "qs" (Query Slop) param for DisMaxRequestHandler
|
||
allows for specifying the amount of default slop to use when parsing
|
||
explicit phrase queries from the user.
|
||
(Adam Hiatt via hossman)
|
||
|
||
16. SOLR-81: SpellCheckerRequestHandler that uses the SpellChecker from
|
||
the Lucene contrib.
|
||
(Otis Gospodnetic and Adam Hiatt)
|
||
|
||
17. SOLR-182: allow lazy loading of request handlers on first request.
|
||
(Ryan McKinley via yonik)
|
||
|
||
18. SOLR-81: More SpellCheckerRequestHandler enhancements, inlcluding
|
||
support for relative or absolute directory path configurations, as
|
||
well as RAM based directory. (hossman)
|
||
|
||
19. SOLR-197: New parameters for input: stream.contentType for specifying
|
||
or overriding the content type of input, and stream.file for reading
|
||
local files. (Ryan McKinley via yonik)
|
||
|
||
20. SOLR-66: CSV data format for document additions and updates. (yonik)
|
||
|
||
21. SOLR-184: add echoHandler=true to responseHeader, support echoParams=all
|
||
(Ryan McKinley via ehatcher)
|
||
|
||
22. SOLR-211: Added a regex PatternTokenizerFactory. This extracts tokens
|
||
from the input string using a regex Pattern. (Ryan McKinley)
|
||
|
||
23. SOLR-162: Added a "Luke" request handler and other admin helpers.
|
||
This exposes the system status through the standard requestHandler
|
||
framework. (ryan)
|
||
|
||
24. SOLR-212: Added a DirectSolrConnection class. This lets you access
|
||
solr using the standard request/response formats, but does not require
|
||
an HTTP connection. It is designed for embedded applications. (ryan)
|
||
|
||
25. SOLR-204: The request dispatcher (added in SOLR-104) can handle
|
||
calls to /select. This offers uniform error handling for /update and
|
||
/select. To enable this behavior, you must add:
|
||
<requestDispatcher handleSelect="true" > to your solrconfig.xml
|
||
See the example solrconfig.xml for details. (ryan)
|
||
|
||
26. SOLR-170: StandardRequestHandler now supports a "sort" parameter.
|
||
Using the ';' syntax is still supported, but it is recommended to
|
||
transition to the new syntax. (ryan)
|
||
|
||
27. SOLR-181: The index schema now supports "required" fields. Attempts
|
||
to add a document without a required field will fail, returning a
|
||
descriptive error message. By default, the uniqueKey field is
|
||
a required field. This can be disabled by setting required=false
|
||
in schema.xml. (Greg Ludington via ryan)
|
||
|
||
28. SOLR-217: Fields configured in the schema to be neither indexed or
|
||
stored will now be quietly ignored by Solr when Documents are added.
|
||
The example schema has a comment explaining how this can be used to
|
||
ignore any "unknown" fields.
|
||
(Will Johnson via hossman)
|
||
|
||
29. SOLR-227: If schema.xml defines multiple fieldTypes, fields, or
|
||
dynamicFields with the same name, a severe error will be logged rather
|
||
then quietly continuing. Depending on the <abortOnConfigurationError>
|
||
settings, this may halt the server. Likewise, if solrconfig.xml
|
||
defines multiple RequestHandlers with the same name it will also add
|
||
an error. (ryan)
|
||
|
||
30. SOLR-226: Added support for dynamic field as the destination of a
|
||
copyField using glob (*) replacement. (ryan)
|
||
|
||
31. SOLR-224: Adding a PhoneticFilterFactory that uses apache commons codec
|
||
language encoders to build phonetically similar tokens. This currently
|
||
supports: DoubleMetaphone, Metaphone, Soundex, and RefinedSoundex (ryan)
|
||
|
||
32. SOLR-199: new n-gram tokenizers available via NGramTokenizerFactory
|
||
and EdgeNGramTokenizerFactory. (Adam Hiatt via yonik)
|
||
|
||
33. SOLR-234: TrimFilter can update the Token's startOffset and endOffset
|
||
if updateOffsets="true". By default the Token offsets are unchanged.
|
||
(ryan)
|
||
|
||
34. SOLR-208: new example_rss.xsl and example_atom.xsl to provide more
|
||
examples for people about the Solr XML response format and how they
|
||
can transform it to suit different needs.
|
||
(Brian Whitman via hossman)
|
||
|
||
35. SOLR-249: Deprecated SolrException( int, ... ) constructors in favor
|
||
of constructors that takes an ErrorCode enum. This will ensure that
|
||
all SolrExceptions use a valid HTTP status code. (ryan)
|
||
|
||
36. SOLR-386: Abstracted SolrHighlighter and moved existing implementation
|
||
to DefaultSolrHighlighter. Adjusted SolrCore and solrconfig.xml so
|
||
that highlighter is configurable via a class attribute. Allows users
|
||
to use their own highlighter implementation. (Tricia Williams via klaas)
|
||
|
||
Changes in runtime behavior
|
||
1. Highlighting using DisMax will only pick up terms from the main
|
||
user query, not boost or filter queries (klaas).
|
||
|
||
2. SOLR-125: Change default of json.nl to flat, change so that
|
||
json.nl only affects items where order matters (facet constraint
|
||
listings). Fix JSON output bug for null values. Internal JAVA API:
|
||
change most uses of NamedList to SimpleOrderedMap. (yonik)
|
||
|
||
3. A new method "getSolrQueryParser" has been added to the IndexSchema
|
||
class for retrieving a new SolrQueryParser instance with all options
|
||
specified in the schema.xml's <solrQueryParser> block set. The
|
||
documentation for the SolrQueryParser constructor and it's use of
|
||
IndexSchema have also been clarified.
|
||
(Erik Hatcher and hossman)
|
||
|
||
4. DisMaxRequestHandler's bq, bf, qf, and pf parameters can now accept
|
||
multiple values (klaas).
|
||
|
||
5. Query are re-written before highlighting is performed. This enables
|
||
proper highlighting of prefix and wildcard queries (klaas).
|
||
|
||
6. A meaningful exception is raised when attempting to add a doc missing
|
||
a unique id if it is declared in the schema and allowDups=false.
|
||
(ryan via klaas)
|
||
|
||
7. SOLR-183: Exceptions with error code 400 are raised when
|
||
numeric argument parsing fails. RequiredSolrParams class added
|
||
to facilitate checking for parameters that must be present.
|
||
(Ryan McKinley, J.J. Larrea via yonik)
|
||
|
||
8. SOLR-179: By default, solr will abort after any severe initalization
|
||
errors. This behavior can be disabled by setting:
|
||
<abortOnConfigurationError>false</abortOnConfigurationError>
|
||
in solrconfig.xml (ryan)
|
||
|
||
9. The example solrconfig.xml maps /update to XmlUpdateRequestHandler using
|
||
the new request dispatcher (SOLR-104). This requires posted content to
|
||
have a valid contentType: curl -H 'Content-type:text/xml; charset=utf-8'
|
||
The response format matches that of /select and returns standard error
|
||
codes. To enable solr1.1 style /update, do not map "/update" to any
|
||
handler in solrconfig.xml (ryan)
|
||
|
||
10. SOLR-231: If a charset is not specified in the contentType,
|
||
ContentStream.getReader() will use UTF-8 encoding. (ryan)
|
||
|
||
11. SOLR-230: More options for post.jar to support stdin, xml on the
|
||
commandline, and defering commits. Tutorial modified to take
|
||
advantage of these options so there is no need for curl.
|
||
(hossman)
|
||
|
||
12. SOLR-128: Upgraded Jetty to the latest stable release 6.1.3 (ryan)
|
||
|
||
Optimizations
|
||
1. SOLR-114: HashDocSet specific implementations of union() and andNot()
|
||
for a 20x performance improvement for those set operations, and a new
|
||
hash algorithm speeds up exists() by 10% and intersectionSize() by 8%.
|
||
(yonik)
|
||
|
||
2. SOLR-115: Solr now uses BooleanQuery.clauses() instead of
|
||
BooleanQuery.getClauses() in any situation where there is no risk of
|
||
modifying the original query.
|
||
(hossman)
|
||
|
||
3. SOLR-221: Speed up sorted faceting on multivalued fields by ~60%
|
||
when the base set consists of a relatively large portion of the
|
||
index. (yonik)
|
||
|
||
4. SOLR-221: Added a facet.enum.cache.minDf parameter which avoids
|
||
using the filterCache for terms that match few documents, trading
|
||
decreased memory usage for increased query time. (yonik)
|
||
|
||
Bug Fixes
|
||
1. SOLR-87: Parsing of synonym files did not correctly handle escaped
|
||
whitespace such as \r\n\t\b\f. (yonik)
|
||
|
||
2. SOLR-92: DOMUtils.getText (used when parsing config files) did not
|
||
work properly with many DOM implementations when dealing with
|
||
"Attributes". (Ryan McKinley via hossman)
|
||
|
||
3. SOLR-9,SOLR-99: Tighten up sort specification error checking, throw
|
||
exceptions for missing sort specifications or a sort on a non-indexed
|
||
field. (Ryan McKinley via yonik)
|
||
|
||
4. SOLR-145: Fix for bug introduced in SOLR-104 where some Exceptions
|
||
were being ignored by all "out of the box" RequestHandlers. (hossman)
|
||
|
||
5. SOLR-166: JNDI solr.home code refactoring. SOLR-104 moved
|
||
some JNDI related code to the init method of a Servlet Filter -
|
||
according to the Servlet Spec, all Filter's should be initialized
|
||
prior to initializing any Servlets, but this is not the case in at
|
||
least one Servlet Container (Resin). This "bug fix" refactors
|
||
this JNDI code so that it should be executed the first time any
|
||
attempt is made to use the solr.home dir.
|
||
(Ryan McKinley via hossman)
|
||
|
||
6. SOLR-173: Bug fix to SolrDispatchFilter to reduce "too many open
|
||
files" problem was that SolrDispatchFilter was not closing requests
|
||
when finished. Also modified ResponseWriters to only fetch a Searcher
|
||
reference if necessary for writing out DocLists.
|
||
(Ryan McKinley via hossman)
|
||
|
||
7. SOLR-168: Fix display positioning of multiple tokens at the same
|
||
position in analysis.jsp (yonik)
|
||
|
||
8. SOLR-167: The SynonymFilter sometimes generated incorrect offsets when
|
||
multi token synonyms were mached in the source text. (yonik)
|
||
|
||
9. SOLR-188: bin scripts do not support non-default webapp names. Added "-U"
|
||
option to specify a full path to the update url, overriding the
|
||
"-h" (hostname), "-p" (port) and "-w" (webapp name) parameters.
|
||
(Jeff Rodenburg via billa)
|
||
|
||
10. SOLR-198: RunExecutableListener always waited for the process to
|
||
finish, even when wait="false" was set. (Koji Sekiguchi via yonik)
|
||
|
||
11. SOLR-207: Changed distribution scripts to remove recursive find
|
||
and avoid use of "find -maxdepth" on platforms where it is not
|
||
supported. (yonik)
|
||
|
||
12. SOLR-222: Changing writeLockTimeout in solrconfig.xml did not
|
||
change the effective timeout. (Koji Sekiguchi via yonik)
|
||
|
||
13. Changed the SOLR-104 RequestDispatcher so that /select?qt=xxx can not
|
||
access handlers that start with "/". This makes path based authentication
|
||
possible for path based request handlers. (ryan)
|
||
|
||
14. SOLR-214: Some servlet containers (including Tomcat and Resin) do not
|
||
obey the specified charset. Rather then letting the the container handle
|
||
it solr now uses the charset from the header contentType to decode posted
|
||
content. Using the contentType: "text/xml; charset=utf-8" will force
|
||
utf-8 encoding. If you do not specify a contentType, it will use the
|
||
platform default. (Koji Sekiguchi via ryan)
|
||
|
||
15. SOLR-241: Undefined system properties used in configuration files now
|
||
cause a clear message to be logged rather than an obscure exception thrown.
|
||
(Koji Sekiguchi via ehatcher)
|
||
|
||
Other Changes
|
||
1. Updated to Lucene 2.1
|
||
|
||
2. Updated to Lucene 2007-05-20_00-04-53
|
||
|
||
================== Release 1.1.0 ==================
|
||
|
||
Status
|
||
------
|
||
This is the first release since Solr joined the Incubator, and brings many
|
||
new features and performance optimizations including highlighting,
|
||
faceted browsing, and JSON/Python/Ruby response formats.
|
||
|
||
|
||
Upgrading from previous Solr versions
|
||
-------------------------------------
|
||
Older Apache Solr installations can be upgraded by replacing
|
||
the relevant war file with the new version. No changes to configuration
|
||
files are needed and the index format has not changed.
|
||
|
||
The default version of the Solr XML response syntax has been changed to 2.2.
|
||
Behavior can be preserved for those clients not explicitly specifying a
|
||
version by adding a default to the request handler in solrconfig.xml
|
||
|
||
By default, Solr will no longer use a searcher that has not fully warmed,
|
||
and requests will block in the meantime. To change back to the previous
|
||
behavior of using a cold searcher in the event there is no other
|
||
warm searcher, see the useColdSearcher config item in solrconfig.xml
|
||
|
||
The XML response format when adding multiple documents to the collection
|
||
in a single <add> command has changed to return a single <result>.
|
||
|
||
|
||
Detailed Change List
|
||
--------------------
|
||
|
||
New Features
|
||
1. added support for setting Lucene's positionIncrementGap
|
||
2. Admin: new statistics for SolrIndexSearcher
|
||
3. Admin: caches now show config params on stats page
|
||
3. max() function added to FunctionQuery suite
|
||
4. postOptimize hook, mirroring the functionallity of the postCommit hook,
|
||
but only called on an index optimize.
|
||
5. Ability to HTTP POST query requests to /select in addition to HTTP-GET
|
||
6. The default search field may now be overridden by requests to the
|
||
standard request handler using the df query parameter. (Erik Hatcher)
|
||
7. Added DisMaxRequestHandler and SolrPluginUtils. (Chris Hostetter)
|
||
8. Support for customizing the QueryResponseWriter per request
|
||
(Mike Baranczak / SOLR-16 / hossman)
|
||
9. Added KeywordTokenizerFactory (hossman)
|
||
10. copyField accepts dynamicfield-like names as the source.
|
||
(Darren Erik Vengroff via yonik, SOLR-21)
|
||
11. new DocSet.andNot(), DocSet.andNotSize() (yonik)
|
||
12. Ability to store term vectors for fields. (Mike Klaas via yonik, SOLR-23)
|
||
13. New abstract BufferedTokenStream for people who want to write
|
||
Tokenizers or TokenFilters that require arbitrary buffering of the
|
||
stream. (SOLR-11 / yonik, hossman)
|
||
14. New RemoveDuplicatesToken - useful in situations where
|
||
synonyms, stemming, or word-deliminater-ing produce identical tokens at
|
||
the same position. (SOLR-11 / yonik, hossman)
|
||
15. Added highlighting to SolrPluginUtils and implemented in StandardRequestHandler
|
||
and DisMaxRequestHandler (SOLR-24 / Mike Klaas via hossman,yonik)
|
||
16. SnowballPorterFilterFactory language is configurable via the "language"
|
||
attribute, with the default being "English". (Bertrand Delacretaz via yonik, SOLR-27)
|
||
17. ISOLatin1AccentFilterFactory, instantiates ISOLatin1AccentFilter to remove accents.
|
||
(Bertrand Delacretaz via yonik, SOLR-28)
|
||
18. JSON, Python, Ruby QueryResponseWriters: use wt="json", "python" or "ruby"
|
||
(yonik, SOLR-31)
|
||
19. Make web admin pages return UTF-8, change Content-type declaration to include a
|
||
space between the mime-type and charset (Philip Jacob, SOLR-35)
|
||
20. Made query parser default operator configurable via schema.xml:
|
||
<solrQueryParser defaultOperator="AND|OR"/>
|
||
The default operator remains "OR".
|
||
21. JAVA API: new version of SolrIndexSearcher.getDocListAndSet() which takes
|
||
flags (Greg Ludington via yonik, SOLR-39)
|
||
22. A HyphenatedWordsFilter, a text analysis filter used during indexing to rejoin
|
||
words that were hyphenated and split by a newline. (Boris Vitez via yonik, SOLR-41)
|
||
23. Added a CompressableField base class which allows fields of derived types to
|
||
be compressed using the compress=true setting. The field type also gains the
|
||
ability to specify a size threshold at which field data is compressed.
|
||
(klaas, SOLR-45)
|
||
24. Simple faceted search support for fields (enumerating terms)
|
||
and arbitrary queries added to both StandardRequestHandler and
|
||
DisMaxRequestHandler. (hossman, SOLR-44)
|
||
25. In addition to specifying default RequestHandler params in the
|
||
solrconfig.xml, support has been added for configuring values to be
|
||
appended to the multi-val request params, as well as for configuring
|
||
invariant params that can not overridden in the query. (hossman, SOLR-46)
|
||
26. Default operator for query parsing can now be specified with q.op=AND|OR
|
||
from the client request, overriding the schema value. (ehatcher)
|
||
27. New XSLTResponseWriter does server side XSLT processing of XML Response.
|
||
In the process, an init(NamedList) method was added to QueryResponseWriter
|
||
which works the same way as SolrRequestHandler.
|
||
(Bertrand Delacretaz / SOLR-49 / hossman)
|
||
28. json.wrf parameter adds a wrapper-function around the JSON response,
|
||
useful in AJAX with dynamic script tags for specifying a JavaScript
|
||
callback function. (Bertrand Delacretaz via yonik, SOLR-56)
|
||
29. autoCommit can be specified every so many documents added (klaas, SOLR-65)
|
||
30. ${solr.home}/lib directory can now be used for specifying "plugin" jars
|
||
(hossman, SOLR-68)
|
||
31. Support for "Date Math" relative "NOW" when specifying values of a
|
||
DateField in a query -- or when adding a document.
|
||
(hossman, SOLR-71)
|
||
32. useColdSearcher control in solrconfig.xml prevents the first searcher
|
||
from being used before it's done warming. This can help prevent
|
||
thrashing on startup when multiple requests hit a cold searcher.
|
||
The default is "false", preventing use before warm. (yonik, SOLR-77)
|
||
|
||
Changes in runtime behavior
|
||
1. classes reorganized into different packages, package names changed to Apache
|
||
2. force read of document stored fields in QuerySenderListener
|
||
3. Solr now looks in ./solr/conf for config, ./solr/data for data
|
||
configurable via solr.solr.home system property
|
||
4. Highlighter params changed to be prefixed with "hl."; allow fragmentsize
|
||
customization and per-field overrides on many options
|
||
(Andrew May via klaas, SOLR-37)
|
||
5. Default param values for DisMaxRequestHandler should now be specified
|
||
using a '<lst name="defaults">...</lst>' init param, for backwards
|
||
compatability all init prams will be used as defaults if an init param
|
||
with that name does not exist. (hossman, SOLR-43)
|
||
6. The DisMaxRequestHandler now supports multiple occurances of the "fq"
|
||
param. (hossman, SOLR-44)
|
||
7. FunctionQuery.explain now uses ComplexExplanation to provide more
|
||
accurate score explanations when composed in a BooleanQuery.
|
||
(hossman, SOLR-25)
|
||
8. Document update handling locking is much sparser, allowing performance gains
|
||
through multiple threads. Large commits also might be faster (klaas, SOLR-65)
|
||
9. Lazy field loading can be enabled via a solrconfig directive. This will be faster when
|
||
not all stored fields are needed from a document (klaas, SOLR-52)
|
||
10. Made admin JSPs return XML and transform them with new XSL stylesheets
|
||
(Otis Gospodnetic, SOLR-58)
|
||
11. If the "echoParams=explicit" request parameter is set, request parameters are copied
|
||
to the output. In an XML output, they appear in new <lst name="params"> list inside
|
||
the new <lst name="responseHeader"> element, which replaces the old <responseHeader>.
|
||
Adding a version=2.1 parameter to the request produces the old format, for backwards
|
||
compatibility (bdelacretaz and yonik, SOLR-59).
|
||
|
||
Optimizations
|
||
1. getDocListAndSet can now generate both a DocList and a DocSet from a
|
||
single lucene query.
|
||
2. BitDocSet.intersectionSize(HashDocSet) no longer generates an intermediate
|
||
set
|
||
3. OpenBitSet completed, replaces BitSet as the implementation for BitDocSet.
|
||
Iteration is faster, and BitDocSet.intersectionSize(BitDocSet) and unionSize
|
||
is between 3 and 4 times faster. (yonik, SOLR-15)
|
||
4. much faster unionSize when one of the sets is a HashDocSet: O(smaller_set_size)
|
||
5. Optimized getDocSet() for term queries resulting in a 36% speedup of facet.field
|
||
queries where DocSets aren't cached (for example, if the number of terms in the field
|
||
is larger than the filter cache.) (yonik)
|
||
6. Optimized facet.field faceting by as much as 500 times when the field has
|
||
a single token per document (not multiValued & not tokenized) by using the
|
||
Lucene FieldCache entry for that field to tally term counts. The first request
|
||
utilizing the FieldCache will take longer than subsequent ones.
|
||
|
||
Bug Fixes
|
||
1. Fixed delete-by-id for field types who's indexed form is different
|
||
from the printable form (mainly sortable numeric types).
|
||
2. Added escaping of attribute values in the XML response (Erik Hatcher)
|
||
3. Added empty extractTerms() to FunctionQuery to enable use in
|
||
a MultiSearcher (Yonik)
|
||
4. WordDelimiterFilter sometimes lost token positionIncrement information
|
||
5. Fix reverse sorting for fields were sortMissingFirst=true
|
||
(Rob Staveley, yonik)
|
||
6. Worked around a Jetty bug that caused invalid XML responses for fields
|
||
containing non ASCII chars. (Bertrand Delacretaz via yonik, SOLR-32)
|
||
7. WordDelimiterFilter can throw exceptions if configured with both
|
||
generate and catenate off. (Mike Klaas via yonik, SOLR-34)
|
||
8. Escape '>' in XML output (because ]]> is illegal in CharData)
|
||
9. field boosts weren't being applied and doc boosts were being applied to fields (klaas)
|
||
10. Multiple-doc update generates well-formed xml (klaas, SOLR-65)
|
||
11. Better parsing of pingQuery from solrconfig.xml (hossman, SOLR-70)
|
||
12. Fixed bug with "Distribution" page introduced when Versions were
|
||
added to "Info" page (hossman)
|
||
13. Fixed HTML escaping issues with user input to analysis.jsp and action.jsp
|
||
(hossman, SOLR-74)
