Subject [jira] Commented: (LUCENE-2094) Prepare CharArraySet for Unicode 4.0
Date Mon, 30 Nov 2009 23:26:20 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2094?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12783938#action_12783938

Robert Muir commented on LUCENE-2094:
-------------------------------------

bq. A godd idea might be to use two StopFilters: 

in theory, but sometimes these terms are ambiguous, and the computer (especially a very simple
analyzer) does not know which one it is, sometimes it can be both. 

sometimes its a real word too, but on average its better to ignore it.

I don't think we need to go to this effort optimal phrasequeries either. A user who really
cares can do this themself... and thats my whole point, they should be able to do something
liek what you said, and explicitly say 'no i don't want posIncr for this stopfilter, but yes
I'll take the real bugfixes, thanks'

> 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.
