$Id$

|
|
|
Apache Solr is an effort undergoing incubation at The Apache Software
|
|
Foundation (ASF), sponsored by Apache Lucene. Incubation is required of all
|
|
newly accepted projects until a further review indicates that the
|
|
infrastructure, communications, and decision making process have stabilized in
|
|
a manner consistent with other successful ASF projects. While incubation status
|
|
is not necessarily a reflection of the completeness or stability of the code,
|
|
it does indicate that the project has yet to be fully endorsed by the ASF.
|
|
|
|
|
|
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)
|
|
|
|
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)
|
|
|
|
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)
|
|
|
|
