Hmm, had a look and think about it and I think I see what you mean by an inverted index. I also think your going to have a real exercise implementing it in Postgres because postgres indexes work on the basis of one tuple, one index entry, which I think your inverted index doesn't do. That said, I think GiST could be extended to support your case without too much difficulty. Interesting project though :) BTW, given you appear to have a tsearch2 index with some real-world data, would you be willing to try some alternate picksplit algorithms to see if your gevel module shows any difference?
