Apache Solr Version 1.4-dev
|
|
Release Notes
|
|
|
|
Introduction
|
|
------------
|
|
Apache Solr is an open source enterprise search server based on the 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 1.5 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
|
|

================== Release 1.4-dev ==================
|
|
Upgrading from Solr 1.3
|
|
-----------------------
|
|
|
|
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.)
|
|
|
|
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. For more
|
|
information, see SOLR-1377.
|

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)
|
|
|
|
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
|
|
DirectoryProvider will use NIOFSDirectory for better concurrency
|
|
on non Windows platforms. (Mark Miller, TJ Laurenzo via yonik)
|
|
|
|
15. SOLR-822: Add CharFilter so that characters can be filtered (e.g. character normalization)
|
|
before Tokenizer/TokenFilters. (koji)
|
|
|
|
16. SOLR-868: Adding solrjs as a contrib package: contrib/javascript.
|
|
(Matthias Epheser via ryan)
|
|
|
|
17. SOLR-829: Allow slaves to request compressed files from master during replication
|
|
(Simon Collins, Noble Paul, Akshay Ukey via shalin)
|
|
|
|
18. SOLR-877: Added TermsComponent for accessing Lucene's TermEnum capabilities.
|
|
Useful for auto suggest and possibly distributed search. Not distributed search compliant. (gsingers)
|
|
- Added mincount and maxcount options (Khee Chin via gsingers)
|
|
|
|
19. SOLR-538: Add maxChars attribute for copyField function so that the length limit for destination
|
|
can be specified.
|
|
(Georgios Stamatis, Lars Kotthoff, Chris Harris via koji)
|
|
|
|
20. SOLR-284: Added support for extracting content from binary documents like MS Word and PDF using Apache Tika. See also contrib/extraction/CHANGES.txt (Eric Pugh, Chris Harris, yonik, gsingers)
|
|
|
|
21. SOLR-819: Added factories for Arabic support (gsingers)
|
|
|
|
22. SOLR-781: Distributed search ability to sort field.facet values
|
|
lexicographically. facet.sort values "true" and "false" are
|
|
also deprecated and replaced with "count" and "lex".
|
|
(Lars Kotthoff via yonik)
|
|
|
|
23. SOLR-821: Add support for replication to copy conf file to slave with a different name. This allows replication
|
|
of solrconfig.xml
|
|
(Noble Paul, Akshay Ukey via shalin)
|
|
|
|
24. SOLR-911: Add support for multi-select faceting by allowing filters to be
|
|
tagged and facet commands to exclude certain filters. This patch also
|
|
added the ability to change the output key for facets in the response, and
|
|
optimized distributed faceting refinement by lowering parsing overhead and
|
|
by making requests and responses smaller.
|
|
|
|
25. SOLR-876: WordDelimiterFilter now supports a splitOnNumerics
|
|
option, as well as a list of protected terms.
|
|
(Dan Rosher via hossman)
|
|
|
|
26. SOLR-928: SolrDocument and SolrInputDocument now implement the Map<String,?>
|
|
interface. This should make plugging into other standard tools easier. (ryan)
|
|
|
|
27. SOLR-847: Enhance the snappull command in ReplicationHandler to accept masterUrl.
|
|
(Noble Paul, Preetam Rao via shalin)
|
|
|
|
28. SOLR-540: Add support for globbing in field names to highlight.
|
|
For example, hl.fl=*_text will highlight all fieldnames ending with
|
|
_text. (Lars Kotthoff via yonik)
|
|
|
|
29. SOLR-906: Adding a StreamingUpdateSolrServer that writes update commands to
|
|
an open HTTP connection. If you are using solrj for bulk update requests
|
|
you should consider switching to this implementaion. However, note that
|
|
the error handling is not immediate as it is with the standard SolrServer.
|
|
(ryan)
|
|
|
|
30. SOLR-865: Adding support for document updates in binary format and corresponding support in Solrj client.
|
|
(Noble Paul via shalin)

|
|
|
|
34. SOLR-943: Make it possible to specify dataDir in solr.xml and accept the dataDir as a request parameter for
|
|
the CoreAdmin create command. (Noble Paul via shalin)
|
|
|
|
35. SOLR-850: Addition of timeouts for distributed searching. Configurable through 'shard-socket-timeout' and
|
|
'shard-connection-timeout' parameters in SearchHandler. (Patrick O'Leary via shalin)
|
|
|
|

|
|
feature in 1.3) (yonik)
|
|
|
|
40. SOLR-940: Add support for Lucene's Trie Range Queries by providing new FieldTypes in
|
|
schema for int, float, long, double and date. Single-valued Trie based
|
|
fields with a precisionStep will index multiple precisions and enable
|
|
faster range queries. (Uwe Schindler, yonik, shalin)
|
|
|
|

|
|
|
|
44. SOLR-1095: Fixed performance problem in the StopFilterFactory and simplified code. Added tests as well. (gsingers)
|
|
|
|
45. SOLR-1096: Introduced httpConnTimeout and httpReadTimeout in replication slave configuration to avoid stalled
|
|
replication. (Jeff Newburn, Noble Paul, shalin)
|
|
|
|
46. SOLR-1115: <bool>on</bool> and <bool>yes</bool> work as expected in solrconfig.xml. (koji)
|
|
|
|
47. SOLR-1099: A FieldAnalysisRequestHandler which provides the analysis functionality of the web admin page as
|
|
a service. The AnalysisRequestHandler is renamed to DocumentAnalysisRequestHandler which is enhanced with

|
|
FieldAnalysisRequestHandler and DocumentAnalysisRequestHandler is also provided in the Solrj client.
|
|
(Uri Boness, shalin)
|
|
|
|

|
|
ord() and rord() functions. (yonik)
|
|
|
|
50. SOLR-1110: Support sorting on trie fields with Distributed Search. (Mark Miller, Uwe Schindler via shalin)
|
|
|
|
51. SOLR-1121: CoreAdminhandler should not need a core . This makes it possible to start a Solr server w/o a core .(noble)
|
|
|
|
52. SOLR-769: Added support for clustering in contrib/clustering. See http://wiki.apache.org/solr/ClusteringComponent for more info. (gsingers, Stanislaw Osinski)

|
|
and it is renamed to locateSolrHome (noble)
|
|
|
|
62. SOLR-1216 : disambiguate the replication command names. 'snappull' becomes 'fetchindex' 'abortsnappull' becomes 'abortfetch' (noble)
|
|
|
|
63. SOLR-1145: Add capability to specify an infoStream log file for the underlying Lucene IndexWriter in solrconfig.xml.
|
|
This is an advanced debug log file that can be used to aid developers in fixing IndexWriter bugs. See the commented
|
|
out example in the example solrconfig.xml under the indexDefaults section.
|
|
(Chris Harris, Mark Miller)
|

|
|
(Robert Muir via yonik)
|

|
66. 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)
|
|
|
|
67. SOLR-1343: Added HTMLStripCharFilter and marked HTMLStripReader, HTMLStripWhitespaceTokenizerFactory and

|
|
high precision date subtraction, add sub() for subtracting other arguments.
|
|
(yonik)
|
|
|
|
73. SOLR-1156: Sort TermsComponent results by frequency (Matt Weber via yonik)

|
|
is the original method. (yonik)
|
|
|

|
|
(Noble Paul via shalin)

|
|
10. SOLR-1166: Speed up docset/filter generation by avoiding top-level
|
|
score() call and iterating over leaf readers with TermDocs. (yonik)
|
|
|
|
11. SOLR-1169: SortedIntDocSet - a new small set implementation
|
|

in the general case. (yonik)
|
|
|
|
12. SOLR-1165: Use Lucene Filters and pass them down to the Lucene
|
|
search methods to filter earlier and improve performance. (yonik)

is both master and slave i.e. when server is a repeater (Akshay Ukey via shalin)
|
|
|
|
32. SOLR-1018: Slave is unable to replicate when server acts as repeater (as both master and slave)
|
|
(Akshay Ukey, Noble Paul via shalin)
|
|
|
|
33. SOLR-1031: Fix XSS vulnerability in schema.jsp (Paul Lovvik via ehatcher)
|
|
|
|

|
|
regardless of what the current core is. (hossman)
|
|
|
|
35. SOLR-1072: absolute paths used in sharedLib attribute were
|

|
|
|
37. SOLR-1125: Use query analyzer rather than index analyzer for queryFieldType in QueryElevationComponent
|
|

|
|
|
|
45. SOLR-1078: Fixes to WordDelimiterFilter to avoid splitting or dropping
|
|
international non-letter characters such as non spacing marks. (yonik)
|
|
|
|
46. SOLR-825: Enables highlighting for range/wildcard/fuzzy/prefix queries if using hl.usePhraseHighlighter=true

|
|
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

|
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)
|
|
|
|

|
|
|
|
37. SOLR-1184: Add option in solrconfig to open a new IndexReader rather than

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:

|
|
|
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)
|
|
|
|
|

|
|
|
================== Release 1.3.0 20080915 ==================
|
|
|
|
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)
|
|
|
|

|
|
|
|
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)

scripts to handle both old and new response format. (bill)
|
|
|
|
9. SOLR-294: Logging of elapsed time broken on Solaris because the date command
|

|
|
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)

|
calculation won't cause overflow. (Thomas Peuss via hossman)
|
|
|
|
20. SOLR-535: Fixed typo (Tokenzied -> Tokenized) in schema.jsp (Thomas Peuss via billa)
|
|
|
|

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

|
|
|

|
|
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)
|
|

|
|
|
|

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)
|
|
|
|
2. SOLR-268: Tweaks to post.jar so it prints the error message from Solr.
|
|
(Brian Whitman via hossman)
|
|
|
|
3. Upgraded to Lucene 2.2.0; June 18, 2007.
|
|

|
4. SOLR-215: Static access to SolrCore.getSolrCore() and SolrConfig.config
|
|
have been deprecated in order to support multiple loaded cores.
|
|
(Henri Biestro via ryan)
|
|
|
|
5. SOLR-367: The create method in all TokenFilter and Tokenizer Factories
|
|
provided by Solr now declare their specific return types instead of just
|
|
using "TokenStream" (hossman)
|
|
|
|
6. SOLR-396: Hooks add to build system for automatic generation of (stub)
|
|

================== Release 1.2, 20070602 ==================
|
|
|
|
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)
|

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>.
|
|
|

|
|
|
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)
