Description

org.apache.solr.request.StandardRequestHandler may parse the query string incorrectly when "stop words" like "and" "of" etc... are used.

We have this query:

Collection:0
AND (Publisher:"Survey"^1 OR Creator:"Survey"^1 OR DocText:"Survey"^3 OR Description:"Survey"^4 OR Title:"Survey"^6)
AND (Publisher:"of"^1 OR Creator:"of"^1 OR DocText:"of"^3 OR Description:"of"^4 OR Title:"of"^6)
AND (Publisher:"Military"^1 OR Creator:"Military"^1 OR DocText:"Military"^3 OR Description:"Military"^4 OR Title:"Military"^6)
AND (Publisher:"Planning"^1 OR Creator:"Planning"^1 OR DocText:"Planning"^3 OR Description:"Planning"^4 OR Title:"Planning"^6)
AND (Publisher:"Systems"^1 OR Creator:"Systems"^1 OR DocText:"Systems"^3 OR Description:"Systems"^4 OR Title:"Systems"^6)

Which got parsed into this query:

+Collection:0
+(Publisher:survey Creator:survey DocText:survey^3.0 Description:survey^4.0 Title:survey^6.0)
+()
+(Publisher:militari Creator:militari DocText:militari^3.0 Description:militari^4.0 Title:militari^6.0)
+(Publisher:plan Creator:plan DocText:plan^3.0 Description:plan^4.0 Title:plan^6.0)
+(Publisher:system Creator:system DocText:system^3.0 Description:system^4.0 Title:system^6.0)

The +() makes the query not work anymore... I am thinking it is is a bug, and if all the terms are removed inside the "(" ")" the "(" ")" should be removed also.
