I've noticed that the search here doesn't perform as well as the regular site searches. Good example: I have a lot of author discussion threads, and sometimes members will write an author's name beginning with last name first (don't ask me why, maybe they were former librarians) and others will write the names first name first. Using the search included with the Batch Update Threads it will only return names exactly as written. So a search for, example, "Tanith Lee" will show only those threads with it written exactly like that in the title. It will not return any threads that have the name written as "Lee, Tanith" in the title. So I always have to do double searches in such cases, to be sure I'm getting them all.
