Bucketing is used to group entries with similar score together with an alphabetical sort. We need to decide how valuable this is and then either improve it or don't bucket at all. per bug 446247 comment 15 "either fix or remove the bucketing, since the current scheme (w/ size > 1) wasn't working well. The ideas we discussed were: - Use some kind of non-linear grouping, since the weights were spanning a large range - Order the first N results (~10?) by totalweight, and make the rest just alphabetical."
