No code, but some small thinking. You can do hacks with boosts and whatnot, but I think in the end you really want a new Query subclass (and the other machinery to make that work). I've seen some of the boost hacks, and, ok, Rocchio is something of a hack (at least the way it's usually done), but adding a hack to a hack is just too much. Next, some joker is going to come along and want to to probabilistic LSI or language models and then you're up the creek ;-) I have a code infrastructure to handle nearly any VSM-style retrieval function (including Okapi BM25), but it's waiting for the low-level VSM query structure to make it worthwhile. If someone starts work in this area, I'd love to help out to the extent I can.
