Subject: [PATCH] BUG FIX: searchpre + empty string failure

A bug exists currently where users can no longer search for an empty string ('') when searchPre is implemented.
Need to explicitly compare the searchPre return to false instead of trusting the ! operator on the string itself as sometimes '' is desired.
