Robert Muir updated LUCENE-2413:
--------------------------------
Attachment: LUCENE-2413_pattern.patch
this patch moves pattern-based components (PatternReplaceFilter,
PatternTokenizer, PatternReplaceCharFilter)
to analysis.pattern package.
the existing PatternAnalyzer in contrib is marked deprecated in favor of this.
additionally, i removed the commons dependency on PatternTokenizer and improved
its performance by reusing a stringbuilder (instead of IOUtils.toString), and
by not creating new strings for group-matching.
> Consolidate all (Solr's & Lucene's) analyzers into contrib/analzyers

> We've been wanting to do this for quite some time now... I think, now that
> Solr/Lucene are merged, and we're looking at opening an unstable line of
> development for Solr/Lucene, now is the right time to do it.
> A standalone module for all analyzers also empowers apps to separately
> version the analyzers from which version of Solr/Lucene they use, possibly
> enabling us to remove Version entirely from the analyzers.
> We should also do LUCENE-2309 (decouple, as much as possible, indexer from
> the analysis API), but I don't think that issue needs to block this
> consolidation.
> Once we do this, there is one place where our users can find all the
> analyzers that Solr/Lucene provide.
