Subject [jira] [Updated] (LUCENE-4381) support unicode 6.2
Date Wed, 12 Sep 2012 23:46:07 GMT


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 :)

out with some interesting features, e.g. dictionary-based CJK segmentation.

automation Steve did as well.
