Subject [jira] [Commented] (LUCENE-4063) FrenchLightStemmer performs abusive compression of (arbitrary) repeated characters in long tokens
Date Thu, 17 May 2012 07:20:11 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4063?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13277635#comment-13277635

Tanguy Moal commented on LUCENE-4063:
-------------------------------------

I'd be glad to see this on 3.x x >=4 since that's the version I used to spot the issue,
may be should I have marked this issue as a bug rather than improvement ? :-)

I have a custom filterfactory marking numbers as keywords anyway as I needed a quick fix.
So from my point of view it doesn't really matter... I could just drop that filter from my
analysis if the patch finds its way to 3x.

Thank you very much for your quick responses about this issue.
