From what I've heard, SwordSearcher is a great tool; I just can't afford to buy it, and I've already plunked down almost $70 for a Mac app.
If you're cheap, go with eSword; that's about as good as it'll ever get for free (and it's already an excellent tool at that). Another 'Doze app I found, though I've never used, is Theophilos (
http://www.theophilos.sk/). If you're thinking outside the box (i.e. "Windoze" box) and use Linux, try GnomeSword; for OS X use the free MacSword or Accordance ($$) if you're a power user.
I'd love to see SwordSearcher for Mac; most "ported" apps aren't that great, but with a Mac-minded UI overhaul I'm sure (from what I've heard) that it would be a top o' the line competitor on the Mac platform.
