Subject [jira] [Commented] (LUCENE-3215) SloppyPhraseScorer sometimes computes Infinite freq
Date Fri, 05 Aug 2011 13:24:27 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3215?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13079964#comment-13079964
] 

Robert Muir commented on LUCENE-3215:
-------------------------------------

It seems to me the root cause of the bug is having position 'holes' (e.g. stopwords), especially
across duplicated terms...

For example, if you disable position increments in queryparser it won't trigger the bug.
