Otis Gospodnetic closed LUCENE-567:
-----------------------------------
Resolution: Won't Fix
> BooleanQuery Does Not Work With One Query indicated as MUST_NOT
> ---------------------------------------------------------------
>
> Key: LUCENE-567
> URL: http://issues.apache.org/jira/browse/LUCENE-567
> Project: Lucene - Java
> Type: Bug
> Components: Search
> Versions: 1.9
> Environment: JDK 1.5, Lucene 1.9.1, Windows XP
> Reporter: Nicholaus Shupe
> Priority: Minor
>
> The following code won't create a boolean query which will return anything
> but a passed in query:
> BooleanQuery result = new BooleanQuery();
> result.add(myQuery, BooleanClause.Occur.MUST_NOT);
> I'll get no results if I use this query. As a workaround, I have to add a
> MatchAllDocsQuery in order to get it to work.
> BooleanQuery result = new BooleanQuery();
> result.add(new MatchAllDocsQuery(), BooleanClause.Occur.SHOULD);
> result.add(myQuery, BooleanClause.Occur.MUST_NOT);
> Maybe this is intended???? If so, perhaps the JavaDocs should be updated to
> indicate this.
