I think it would add bloat plus it would be extremely slow without access to the database (which Mark mentioned he's not using).
If you're going to search individual documents you'd want to generate some type of index to really speed up the search. And that seems a little redundant considering we already have the database (again, which isn't being used by hijack right now).
Hey, maybe someone wants to install
HT://dig on their player and then see if they can get it to play nice with Hijack. Then you can get your results ranked for relevance as well.
Mark mentioned in another thread that if someone wanted to figure out the specifics on the database format that he would consider supporting it for much increased playlist generation speeds.
