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
