Subject [jira] Commented: (LUCENE-2094) Prepare CharArraySet for Unicode 4.0
Date Mon, 30 Nov 2009 18:19:20 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2094?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12783773#action_12783773
] 

Uwe Schindler commented on LUCENE-2094:
---------------------------------------

bq. its not clear from the Solr issue that added this option either.

Because they wanted to preserve bw compatibility for old indexes. And at this time Version
was not available. Newer versions of Solr should just add a property to their factories giving
the version (or a global solr option automatically applied to the whole Solr installation;
that how I do it in panFMP, my own Solr-like project).

bq. Or if its considered a bug that posInc wasn't working before. 

It is a bug.

> 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.
