was this finally filled in a jira issue? I'm experiencing the same problem.
With default q.op=AND "q:xxx zzz" behaves as expected --> "xxx AND zzz" "q:(xxx AND yyy) zzz" behaves as expected --> "(xxx AND yyy) AND zzz "q:(xxx OR yyy) zzz" changes the default operator to OR like --> "(xxx OR yyy) OR zzz" 2012/12/13 Jack Krupansky <j...@basetechnology.com> > &debug=query -- Juan Miguel Cejuela
