Otis Gospodnetic commented on LUCENE-736:
-----------------------------------------
Doron, sounds like this is ripe for a commit now to take care of both this and LUCENE-697.
> Sloppy Phrase Scoring Misbehavior

> This is an extension of https://issues.apache.org/jira/browse/LUCENE-697
> In addition to abnormalities Yonik pointed out in 697, there seem to be other issues with slopy phrase search and scoring.
> 1) A phrase with a repeated word would be detected in a document although it is not there.
> I.e. document = A B D C E , query = "B C B" would not find this document (as expected), but query "B C B"~2 would find it.
> I think that no matter how large the slop is, this document should not be a match.
> 2) A document containing both orders of a query, symmetrically, would score differently for the queru and for its reveresed form.
> I.e. document = A B C B A would score differently for queries "B C"~2 and "C B"~2, although it is symmetric to both.
> I will attach test cases that show both these problems and the one reported by Yonik in 697.
