Today's logs were filled with more than 7,000 instances of warnings like "open-ils.storage.biblio.multiclass.staged.search_fts: Argument "INNER" isn't numeric in numeric ne (!=) at /usr/local/share/perl/5.10.1/OpenILS/Application/Storage/Driver/Pg/QueryParser.pm line 949."

The problem is that a numeric comparison is being used where a string comparison operator should instead be used. Solved in:
