Robert Muir updated LUCENE-4381:
--------------------------------

    Attachment: LUCENE-4381.patch

A hacked up patch for testing:

I think its nice to offer the CJK dictionary-based stuff as an option? I'm not 
sure how good results will be on average yet (maybe I can enlist Christian to 
help investigate).

So as a test I just added a boolean option, which if enabled, keeps all 
han/hiragana/katakana marked as "Chinese/Japanese" (uses the 15924 Japanese 
code, but I overrode the toString to try to prevent confusion).

Seems to work ok: some trivial snippets from smartcn and kuromoji are analyzed 
fine, and testRandomStrings is happy :)

> ICU will release a new version in about a month.
> They have a version for testing 
> (http://site.icu-project.org/download/milestone) already out with some 
> interesting features, e.g. dictionary-based CJK segmentation.
> This issue is just to test it out/integrate the new stuff/etc. We should try 
> out the automation Steve did as well.
