["Grant Ingersoll (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-1142?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12623688#action_12623688 ] 

Grant Ingersoll commented on LUCENE-1142:
-----------------------------------------

Karl,

This is marked as 2.4, but your comment suggests 3.0.  Which do you prefer?  We are, again, in that tricky spot of how to handle changes where the API is compatible, but the index can change.

One thing to check, maybe, is how many terms are going to be affected?   Maybe we put this in now and we mark it in CHANGES.txt that users of Snowball will need to re-index, or at least thoroughly test to see if there are any issues in their setup.  

I can go either way.

> Updated Snowball contrib package
>  * New org.tartarus.snowball java package with patched SnowballProgram to be abstract to avoid using reflection.
>  * Introducing Hungarian, Turkish and Romanian stemmers
>  * Introducing constructor SnowballFilter(SnowballProgram)
> It is possible there have been some changes made to the some of there stemmer algorithms between this patch and the current SVN trunk of Lucene, an index might thus not be compatible with new stemmers!
> The API is backwards compatibile and the test pass.
