Robert Muir updated SOLR-2108:
------------------------------
Attachment: SOLR-2108.patch
Simple fix: if we are doing a wildcard query on a reversed field, but we
*are not* going to reverse it, we must subtract the set of reversed terms
(markerChar*) from the query dfa as these could be false positives.
I also added a basic test.
