Unfortunately this makes some searches for short words return bad results, because they match a lot of words that aren't related to what the user actually wants. I'm wondering if there's a good way to make specific matches get a higher weight than longer words?

Could you parse the query twice, once with wildcard turned on, once without, and adjust the relative weighting of the two queries when you combine them?
