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.
> BooleanQuery can not find all matches in special condition

> Key: LUCENE-1974
> URL: https://issues.apache.org/jira/browse/LUCENE-1974
> Project: Lucene - Java
> Issue Type: Bug
> Components: Query/Scoring
> Affects Versions: 2.9
> Reporter: tangfulin
> Attachments: BooleanQueryTest.java, LUCENE-1974.test.patch
>
>
> query: (name:tang*)
> doc=5137 score=1.0 doc:Document<stored,indexed<name:tangfulin>>
> doc=11377 score=1.0 doc:Document<stored,indexed<name:tangfulin>>
> query: name:tang* name:notexistnames
> doc=5137 score=0.048133932 doc:Document<stored,indexed<name:tangfulin>>
> It is two queries on the same index, one is just a prefix query in a
> boolean query, and the other is a prefix query plus a term query in a
> boolean query, all with Occur.SHOULD .
> what I wonder is why the later query can not find the doc=11377 doc ?
> the problem can be repreduced by the code in the attachment .
