RE: Limiting a search by URL

Left-hand truncation is quite expensive and not well supported.  I think
you'd be much better off suggesting that the URL's be parsed into words.  At
that point, you could decide whether you needed proximity searching between
the words, but I doubt it; there are few chances of bad hits and the
potential for catching word reversals.

What you lose is the ability to search for "*nasa*" which will get things by
nasa and anything to do with nasau and nasal drip.  Instead, you will search
on "nasa" and only get things related to nasa.
