Is this not one of the most useful things ever?! I have a large library, and it took a long time to finish and that index file is really large, but MAN! Totally worth it! Search capability has been improved massively now! I just have to think of anything vaguely related to whatever I am looking for and BAM! Found! I've tried doing this sort of thing in the past at various times using obscure, crash-prone indexer programs on Windows and Linux, but this works way better than those did, no crashes during process, and it seems to have indexed all the various formats.
