Lee Hinman created LUCENE-6304:
----------------------------------
Summary: Add MatchNoDocsQuery that matches no documents
Key: LUCENE-6304
URL: https://issues.apache.org/jira/browse/LUCENE-6304
Project: Lucene - Core
Issue Type: Improvement
Components: core/search
Affects Versions: 5.0
Reporter: Lee Hinman
Priority: Minor
As a followup to LUCENE-6298, it would be nice to have an explicit
MatchNoDocsQuery to indicate that no documents should be matched. This would
hopefully be a better indicator than a BooleanQuery with no clauses or (even
worse) null.
