This looks kind of like it could be handled with a logical OR for the most part? The idea of being able to run mathematical operations on tabbles is definitely intriguing but I wonder if it might either balloon the size of the DB or slow down the program if not narrowly implemented – possibly via a separate search panel?

I have asked for auto-tagging based on file date and time (though it hasn’t made it into release yet…) would that help you in any way?
