The tweak I made was included in build 33; however, it should only affect how "intuitive" the search suggestions are. I have a hunch (feel free to correct me if I'm wrong) that you're referring to the actual matching Play Doctor uses when finding similar tracks to the search query. If this is what you're referring to, that's actually a different part of the program than what I was working on. You are right that it uses an external database to select similar tracks, though. So, that might be the source of some strange matches.
