Karsten R. commented on LUCENE-4109:
------------------------------------
other differences between classic QueryParser and flexible StandardQueryParser
can be seen, if we run QueryParserTestBase against StandardQueryParser:
* assertQueryEquals("[\\* TO \"*\"]",null,"[\\* TO \\*]");
→ result is {{ "[\\* TO *]" }} instead
* {{{ assertQueryEquals("a:b\\-?c", a, "a:b\\-?c"); }}}
→ result is {{{ "a:b-?c" }}} instead
* assertQueryEquals("a - b", a, "a – b"); }}
→ LUCENE-2566
Is it possible to backport a solution to 3.x? I have a customer with this exact
problem on 3.6...

> 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.
