[jira] Commented: (LUCENE-1310) Phrase query with term repeated 3
times requires more slop than expected
[ https://issues.apache.org/jira/browse/LUCENE-1310?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12619339#action_12619339 ]
Doron Cohen commented on LUCENE-1310:
-------------------------------------
Committed to trunk.
I was wondering if this should be backported to 2.3.1 and/or 2.3.2.
It is not a major bug so I think not, though it might be critical to some application.
Didn't find a guideline for this in the wiki but I may be missing it?

> Project: Lucene - Java
> Issue Type: Bug
> Components: Search
> Affects Versions: 2.3.1, 2.3.2
> Reporter: Grant Glouser
> Assignee: Doron Cohen
> Attachments: LUCENE-1310.1.patch, LUCENE-1310.patch, LUCENE-1310.patch, LUCENE-1310.patch, LUCENE-1310.patch, LUCENE-1310.patch, LUCENE-2.3.1-1310.patch, TestSloppyPhraseQuery.java

> Consider a document with the text "A A A".
> The phrase query "A A A" (exact match) succeeds.
> The query "A A A"~1 (same document and query, just increasing the slop value by one) fails.
> "A A A"~2 succeeds again.
> If the exact match succeeds, I wouldn't expect the same query but with more slop to fail. The fault seems to require some term to be repeated at least three times in the query, but the three occurrences do not need to be adjacent. I will attach a file that contains a set of JUnit tests that demonstrate what I mean.
