That's a good question.

Currently the relevance feedback in Xapian always uses the formula which
is equivalent to "TradWeight" document weighting.  But it's abstracted to
an ExpandWeight class internally, so plugging in other formulae wouldn't
be too hard if they are expressible in a suitable form.

I think it's up to you whether you want to tackle that as part of this
project or not.

Heh.

I've not come across the "Million Song Dataset" before - that looks an
interesting resource:
