This is really cool! And quite simple too!
So now I suppose the test would be to try with some real world examples :)
I don't know the kind of tests we can write for this though.
If the results are convincing enough, I'd agree with you: we can first
settle for SQLite before moving to something more sophisticated like
Xapian.
Cheers!
