I said up-thread, and I repeat: all of the measures to make the potential number of hits larger will backfire as long as we don't have a good scoring system that almost always puts the most probable hits in the first dozen. No, I don't have an algorithm for that; I'm not an expert in this field. But I do know it's possible, because I see it every day when I search the Internet.
