Subject [jira] [Commented] (LUCENE-3821) SloppyPhraseScorer sometimes misses documents that ExactPhraseScorer finds.
Date Sun, 04 Mar 2012 12:29:58 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3821?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13221867#comment-13221867
] 

Doron Cohen commented on LUCENE-3821:
-------------------------------------

Update: apparently MultiPhraseQuery.toString does not print its "holes".

So the query that failed was not:
{noformat}field:"(j o s) (i b j) (t d)"{noformat}

But rather:
{noformat}"(j o s) ? (i b j) ? ? (t d)"{noformat}

Which is a different story: this query should match the document
{noformat}s o b h j t j z o{noformat}

There is a match for ExactPhraseScorer, but not for Sloppy with slope 1.
So there is still work to do on SloppyPhraseScorer...

(I'll fix MFQ.toString() as well)

> The general bug is a case where a phrase with no slop is found,
> but if you add slop its not.
> I committed a test today (TestSloppyPhraseQuery2) that actually triggers this case,
> jenkins just hasn't had enough time to chew on it.
> ant test -Dtestcase=TestSloppyPhraseQuery2 -Dtests.iter=100 is enough to make it fail
on trunk or 3.x
