Steven,

Christoph
> MUST_NOT query always retunrs no documents
> ------------------------------------------
>
> Key: LUCENE-2714
> URL: https://issues.apache.org/jira/browse/LUCENE-2714
> Project: Lucene - Java
> Issue Type: Bug
> Components: Query/Scoring
> Affects Versions: 2.9.3
> Reporter: Christoph Schmidt
>
> The following two queries are logically equal, but return different document
> results:
> query1 = +body:term -id:17
> query2 = +(+body:term) +(-id:17)
> query1 returns all documents containing term in the field body not having id
> 17.
> query2 returns no documents
> Maybe is a kind of optimization that documents with score = 0.0 are ignored?
> query3 = +(+body:term) +(+*:* -id:17)
> has the same result as query1 again.
> Thanks for help.
> Best regards
> Christoph Schmidt
