Subject [jira] Updated: (LUCENE-1974) BooleanQuery can not find all matches in special condition
Date Tue, 13 Oct 2009 22:55:31 GMT


Hoss Man updated LUCENE-1974:

    Attachment: LUCENE-1974.test.patch

this is the same as the previously attached test but i've simplified it (to me) and revamped
it to be a patch that can be applied to 2.9.0.

I can confirm that it fails for me (against 2.9.0) and seems to suggest a weird hit collection
bug somwhere in the BooleanScorer or Prefix scoring code 

(a prefix query works, a boolean query containing term queries work, but a boolean query containing
a prefix query fails to find all the expected matches)

Unless i'm missing something really silly, this suggests a pretty heinious bug somewhere in
the core scoring code.
