Subject [jira] Commented: (LUCENE-2094) Prepare CharArraySet for Unicode 4.0
Date Sun, 29 Nov 2009 14:09:20 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2094?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12783406#action_12783406
] 

Simon Willnauer commented on LUCENE-2094:
-----------------------------------------

bq. I guess i think this getEnablePositionIncrementsVersionDefault should be deprecated along
with the ctors that take this boolean argument, and it should all be driven off a single Version
argument for simplicity

This is one thing I thought about too - I did not change it to keep the noise as low as possible
in the patch but if we want to do it we can do in this patch too. 

The question if we want to drop bw. compat and simply update CharArraySet to Unicode 4.0 seems
to be more important. But IMO if we push Version to StopFilter we can also make CharArraySet
using Version though.

thoughts?

> CharArraySet does lowercaseing if created with the correspondent flag. This causes that
 String / char[] with uncode 4 chars which are in the set can not be retrieved in "ignorecase"
mode.
