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. (Note: standard request handler does
|
|
not currently do anything with term vectors) (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)
|
|
|
|
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
|
|
|
|
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)
|
|
|
|
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
|
|
|
|
