: Perhaps you can solve your usecase by playing with the new eDismax : "boost" parameter, which multiplies the functions with the other score : instead of adding.
and FWIW: the "boost" param of the edismax parser is really just syntactic
sugar for using the "BoostQParsre wrapped arround an edismax query -- you
can wrap it around any query produced by any QParser...
q={!edismax qf=foo}bar&boost=func(asdf)
...is the same as...
q={!boost b=func(asdf) v=$qq}&qq={!edismax qf=foo}bar
