API Changes
|
|
|
|
* LUCENE-3820: Deprecated constructors accepting pattern matching bounds. The input
|
|
is buffered and matched in one pass. (Dawid Weiss)
|
|
|
|
* 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)
|
|
|
|
* LUCENE-1370: Added ShingleFilter option to output unigrams if no shingles
|
|
can be generated. (Chris Harris via Steven Rowe)
|
|
|
|
* 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)
|
|
|
|
* LUCENE-3400: Removed DutchAnalyzer.setStemDictionary (Chris Male)
|
|
|
|
* LUCENE-3431: Removed QueryAutoStopWordAnalyzer.addStopWords* deprecated methods
|
|
since they prevented reuse. Stopwords are now generated at instantiation through
|
|
the Analyzer's constructors. (Chris Male)
|
|
|
|
* LUCENE-3434: Removed ShingleAnalyzerWrapper.set* and PerFieldAnalyzerWrapper.addAnalyzer
|
|
since they prevent reuse. Both Analyzers should be configured at instantiation.
|
|
(Chris Male)
|
|
|
|
* 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.
|
|
(Dawid Weiss)
|
|
|
|
New Features
|
|
|
|
* LUCENE-2341: A new analyzer/ filter: Morfologik - a dictionary-driven lemmatizer
|
|
(accurate stemmer) for Polish (includes morphosyntactic annotations).
|
|
(Michał Dybizbański, Dawid Weiss)
|
|
|
|
* LUCENE-2413: Consolidated Lucene/Solr analysis components into common.
|
|
New features from Solr now available to Lucene users include:
|
|
- o.a.l.analysis.commongrams: Constructs n-grams for frequently occurring terms
|
|
and phrases.
|
|
- o.a.l.analysis.charfilter.HTMLStripCharFilter: CharFilter that strips HTML
|
|
constructs.
|
|
- o.a.l.analysis.miscellaneous.WordDelimiterFilter: TokenFilter that splits words
|
|
into subwords and performs optional transformations on subword groups.
|
|
- o.a.l.analysis.miscellaneous.RemoveDuplicatesTokenFilter: TokenFilter which
|
|
filters out Tokens at the same position and Term text as the previous token.
|
|
- o.a.l.analysis.miscellaneous.TrimFilter: Trims leading and trailing whitespace
|
|
from Tokens in the stream.
|
|
- o.a.l.analysis.miscellaneous.KeepWordFilter: A TokenFilter that only keeps tokens
|
|
with text contained in the required words (inverse of StopFilter).
|
|
- o.a.l.analysis.miscellaneous.HyphenatedWordsFilter: A TokenFilter that puts
|
|
hyphenated words broken into two lines back together.
|
|
- o.a.l.analysis.miscellaneous.CapitalizationFilter: A TokenFilter that applies
|
|
capitalization rules to tokens.
|
|
- o.a.l.analysis.pattern: Package for pattern-based analysis, containing a
|
|
CharFilter, Tokenizer, and Tokenfilter for transforming text with regexes.
|
|
- o.a.l.analysis.synonym.SynonymFilter: A synonym filter that supports multi-word
|
|
synonyms.
|
|
- o.a.l.analysis.phonetic: Package for phonetic search, containing various
|
|
phonetic encoders such as Double Metaphone.
|
|
|
|
