RE: FW: Score customization
I effectively need to use a multiplication in the sorting of the items.
Something like score*popularity.
It seems the only way to do this is to use a bf parameter.
However how do you use bf in combination with the standard requestHandler?

functions are understood by the standard query parser using the
_val_:"func(...)" hack...

You could use function query with standardRequestHandler to influence
the final score and sort result by score. If you want to control how
much the function query would affect the original score, you could use
the linear function.
