I've got a similar question; but would love a dictionary that
could give me an efficient index that considers that
Bill/William and Bob/Rob/Robert and Khadaffi/Qaddafi might
share the same roots. Ideally it'd return exact matches
first, followed by the similar terms.

I kludged up some many step queries to try to do this; but
wonder if this would work better as a tsearch dictionary,
and wonder even more if I'm re-inventing something that's
already out there.

Anyone know of such a tsearch dictionary that is aware of
the roots of names?
