Subject [jira] Commented: (SOLR-1804) Upgrade Carrot2 to 3.2.0
Date Mon, 15 Mar 2010 19:27:27 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1804?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12845474#action_12845474

Robert Muir commented on SOLR-1804:
-----------------------------------

Thanks for the confirmation the clusters are ok.

Well, this is embarrassing, it turns out it is a backwards break, 
though documented, and the culprit is yours truly.

This is the reason it gets different results:
{noformat}
* LUCENE-2286: Enabled DefaultSimilarity.setDiscountOverlaps by default.
  This means that terms with a position increment gap of zero do not
  affect the norms calculation by default.  (Robert Muir)
{noformat}

I'll change the test to expect 15 clusters with Lucene 3.1, thanks :)
