Subject [jira] [Updated] (LUCENE-3821) SloppyPhraseScorer sometimes misses documents that ExactPhraseScorer finds.
Date Sun, 04 Mar 2012 00:17:58 GMT


Doron Cohen updated LUCENE-3821:

    Attachment: LUCENE-3821.patch

Patch with fix for this problem. I would expect SloppyPhrase scoring performance to degrade,
though I did not measure it.

The single test that still fails (and I think the bug is in ExactPhraseScorer) is testRandomIncreasingSloppiness,
and can be recreated like this:
ant test -Dtestcase=TestSloppyPhraseQuery2 -Dtestmethod=testRandomIncreasingSloppiness -Dtests.seed=47267613db69f714:-617bb800c4a3c645:-456a673444fdc184

> 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
