API Changes
|
|
|
|
|
|
2012-02-27 08:13:10 -05:00
|
|
|
* LUCENE-3820: Deprecated constructors accepting pattern matching bounds. The input
|
|
|
|
|
is buffered and matched in one pass. (Dawid Weiss)
|
|
|
|
|
|
2010-05-05 12:27:58 -04:00
|
|
|
* LUCENE-2413: Deprecated PatternAnalyzer in common/miscellaneous, in favor
|
|
|
|
|
of the pattern package (CharFilter, Tokenizer, TokenFilter). (Robert Muir)
|
|
|
|
|
|
|
|
|
|
* LUCENE-2413: Removed the AnalyzerUtil in common/miscellaneous. (Robert Muir)
|
|
|
|
|
|
2010-10-09 12:55:23 -04:00
|
|
|
* LUCENE-1370: Added ShingleFilter option to output unigrams if no shingles
|
|
|
|
|
can be generated. (Chris Harris via Steven Rowe)
|
|
|
|
|
|
2011-02-28 00:15:50 -05:00
|
|
|
* LUCENE-2514, LUCENE-2551: JDK and ICU CollationKeyAnalyzers were changed to
|
|
|
|
|
use pure byte keys when Version >= 4.0. This cuts sort key size approximately
|
|
|
|
|
in half. (Robert Muir)
|
2011-08-25 06:32:21 -04:00
|
|
|
|
|
|
|
|
* LUCENE-3400: Removed DutchAnalyzer.setStemDictionary (Chris Male)
|
2011-09-07 00:43:10 -04:00
|
|
|
|
2011-09-13 23:33:50 -04:00
|
|
|
* LUCENE-3431: Removed QueryAutoStopWordAnalyzer.addStopWords* deprecated methods
|
|
|
|
|
since they prevented reuse. Stopwords are now generated at instantiation through
|
|
|
|
|
the Analyzer's constructors. (Chris Male)
|
|
|
|
|
|
2011-09-14 23:21:17 -04:00
|
|
|
* LUCENE-3434: Removed ShingleAnalyzerWrapper.set* and PerFieldAnalyzerWrapper.addAnalyzer
|
|
|
|
|
since they prevent reuse. Both Analyzers should be configured at instantiation.
|
|
|
|
|
(Chris Male)
|
|
|
|
|
|
2012-02-09 14:59:50 -05:00
|
|
|
* LUCENE-3765: Stopset ctors that previously took Set<?> or Map<?,String> now take
|
|
|
|
|
CharArraySet and CharArrayMap respectively. Previously the behavior was confusing,
|
|
|
|
|
and sometimes different depending on the type of set, and ultimately a CharArraySet
|
|
|
|
|
or CharArrayMap was always used anyway. (Robert Muir)
|
|

|
|
|
Bug fixes
|
|
|
|
|
|
|
|
|
|
* LUCENE-3820: PatternReplaceCharFilter could return invalid token positions.
|
|
|
|
|

|
|
|
|
|
(accurate stemmer) for Polish (includes morphosyntactic annotations).
|
|
|
|
|
(Michał Dybizbański, Dawid Weiss)
