a nice feature would be similar to what searching google books does. the results highlight in yellow (though I'd prefer a way to clear highlighting after seeing where I'm supposed to stare)
I searched for "MUDs" and found a few results, clicked one, but it didn't appear the centered page was the one I was looking for
this is a wonderful idea though, and I'm happy you made it!
edit: perhaps also a nice feature is putting the search query in the URL, so I can link folks
