---------------------------------------
Hi Robert,
All fine. No more problems found!
> add icu-based tokenizer for unicode text segmentation
> -----------------------------------------------------

> Key: LUCENE-2414
> URL: https://issues.apache.org/jira/browse/LUCENE-2414
> Project: Lucene - Java
> Issue Type: New Feature
> Components: contrib/*
> Affects Versions: 3.1
> Reporter: Robert Muir
> Fix For: 3.1
>
> Attachments: LUCENE-2414.patch, LUCENE-2414.patch, LUCENE-2414.patch,

> I pulled out the last part of LUCENE-1488, the tokenizer itself and cleaned
> it up some.
> The idea is simple:
> * First step is to divide text into writing system boundaries (scripts)
> * You supply an ICUTokenizerConfig (or just use the default) which lets you
> tailor segmentation on a per-writing system basis.
> * This tailoring can be any BreakIterator, so rule-based or dictionary-based
> or your own.
> The default implementation (if you do not customize) is just to do UAX#29,
> but with tailorings for stuff with no clear word division:
> * Thai (uses dictionary-based word breaking)
> * Khmer, Myanmar, Lao (uses custom rules for syllabification)
> Additionally as more of an example i have a tailoring for hebrew that treats
> the punctuation special. (People have asked before
> for ways to make standardanalyzer treat dashes differently, etc)
