Document boosting not supported

[mjl]

Document boosting is not supported with the xapian backend:

As per the docs I added things like this:

def prepare(self, obj):
    data = super(OfferSearchIndex, self).prepare(obj)
    data['boost'] = 1.25
    return data

to my SearchIndex subclasses, but the order / score of the results is totally unchanged.

Not sure how this can be done with the current Xapian API. Will investigate further to see if it's possible, and how.

+1 on this, it would be a nice feature to have, maybe it has some relation with weighting scheme #99 ?

any improvements on this? it's something I need too.
