Karsten R. commented on LUCENE-4109:
------------------------------------
Robert, the current GroupQueryNodeProcessor minimize the amount of nodes in the
SyntaxTree (via defaultOperator).
I think this screw me up. I could make a patch without this optimization which
passes TestQPHelper.
But possible we need more TestCases. I would like to test against
QueryParserTestBase, but this can not be extended for StandardQueryParser
because of the defaultField, which moves from constructor to the parse-method
and because there is no common interface for classic QP and StandardQP with
e.g. the setAllowLeadingWildcard-Method.
Would it be OK, if I also patch QueryParserTestBase?

> Hi,
> I just found another bug in the flexible query parser (together with Robert
> Muir, yay!).
> The following query string works in the standard query parser:
> {noformat}
> (field:[1 TO *] AND field:[* TO 2]) AND field2:z
> {noformat}
> yields
> {noformat}
> +(+field:[1 TO *] +field:[* TO 2]) +field2:z
> {noformat}
> The flexible query parser though yields:
> {noformat}
> +(field:[1 TO *] field:[* TO 2]) +field2:z
> {noformat}
> Test patch is attached (from Robert actually).
> I don't know if it affects earlier versions than 3.5.
