[jira] [Comment Edited] (LUCENE-6249) StandardQueryParser doesn't support pure negative clauses

    [ https://issues.apache.org/jira/browse/LUCENE-6249?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14322802#comment-14322802 ]

--------------------------------------------------------------

The problem doesn't seem to be with the grammar, but with query building after the parse tree is acquired.

The tree is fine:
{code}
<modifier operation='MOD_NOT'>
<field start='9' end='12' field='summary' text='foo'/>
</modifier>
{code}

but it eventually goes to a single ModifierQueryNodeBuilder which just returns the unmodified underlying query. I don't fully understand the parser, looking into it.

> At first I thought it's by design but Uwe says it's a bug. SQP emits this:

> StandardQueryParser qp = new StandardQueryParser();
> qp.setDefaultOperator(Operator.AND);
>    
> System.out.println(qp.parse("summary:foo", "deffld"));
> System.out.println(qp.parse("-summary:foo", "deffld"));
> System.out.println(qp.parse("!summary:foo", "deffld"));
> System.out.println(qp.parse("NOT summary:foo", "deffld"));
> {code}
> {code}
> summary:foo
> summary:foo
> summary:foo
> summary:foo
> {code}
