Doron Cohen updated LUCENE-1310:
--------------------------------

    Attachment: LUCENE-1310.patch

Updated patch fixes this issue. 
In case of repeating terms in the query, this might be slower than previous patch, \
but it is supposedly correct in all cases while the previous one was not guaranteed \
to be always correct. There are no performance implications for the more common case \
of no repeating terms in the query. I plan to commit this in a day or two.


> Phrase query with term repeated 3 times requires more slop than expected

> Key: LUCENE-1310
> URL: https://issues.apache.org/jira/browse/LUCENE-1310
> 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, 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.
