|
|
3. LUCENE-1510: InstantiatedIndexReader#norms methods throws NullPointerException on empty index.

|
|
|
4. LUCENE-1514: ShingleMatrixFilter#next(Token) easily throws a StackOverflowException
|
|
due to recursive invocation. (Karl Wettin)
|
|
|
|
5. LUCENE-1548: Fix distance normalization in LevenshteinDistance to
|
|
not produce negative distances (Thomas Morton via Mike McCandless)
|
|
|
|
6. LUCENE-1490: Fix latin1 conversion of HALFWIDTH_AND_FULLWIDTH_FORMS
|
|
characters to only apply to the correct subset (Daniel Cheng via

New features
|
|
|
|
1. LUCENE-1531: Added support for BoostingTermQuery to XML query parser. (Karl Wettin)
|
|
|
|
2. LUCENE-1435: Added contrib/collation, a CollationKeyFilter
|
|
allowing you to convert tokens into CollationKeys encoded usign
|
|
IndexableBinaryStringTools. This allows for faster RangQuery when
|
|
a field needs to use a custom Collator. (Steven Rowe via Mike
|
|
McCandless)
|
|
|
|
3. LUCENE-1591: EnWikiDocMaker, LineDocMaker, WriteLineDoc can now
|
|
read/write bz2 using Apache commons compress library. This means
|
|
you can download the .bz2 export from http://wikipedia.org and
|
|
immediately index it. (Shai Erera via Mike McCandless)
|
|
|
|
4. LUCENE-1629: Add SmartChineseAnalyzer to contrib/analyzers. It
|
|
improves on CJKAnalyzer and ChineseAnalyzer by handling Chinese
|
|
sentences properly. SmartChineseAnalyzer uses a Hidden Markov
|
|
Model to tokenize Chinese words in a more intelligent way.
|
|
(Xiaoping Gao via Mike McCandless)
|
|
|
|
5. LUCENE-1676: Added DelimitedPayloadTokenFilter class for automatically adding payloads "in-stream" (Grant Ingersoll)

|
|
constructor of InstantiatedIndex. (Karl Wettin)
|
|
|
|
Optimizations
|
|
|
|
1. LUCENE-1643: Re-use the collation key (RawCollationKey) for
|
|
better performance, in ICUCollationKeyFilter. (Robert Muir via
|
|
Mike McCandless)
