Subject [jira] Commented: (LUCENE-492) PhraseQuery.explain is broken

Hoss Man commented on LUCENE-492:
---------------------------------

Aparently Yonik and i wre both hallucinating -- because both of us saw bad explain output
coming form my application, but now i can't reproduce it in an issolated test case, and I
can't even reproduce it in my app.

> PhraseQuery's explain method returns bogus scores in the case where the phrase doesn't
match.  Unless i'm crazy, it can even indicate a match when one of the terms doesn't even
appear in the document.
> This can be particularly confusing when looking at the explain output for a doc that
matches a large boolean query in spite of failing to match on a PhraseQuery which is part
of that BQ.
> I'll try to attach an isolated test case shortly.
