[jira] [Commented] (LUCENE-3215) SloppyPhraseScorer sometimes computes Infinite freq

    [ 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.
