Oops.. this will only help you configure only the defaults common to the
main dismax query as well as the fq dismax query.
For creating two sets of dismax parsers which are named and want to read
params from solrconfig, I think one can extend the dismaxQParser's currently
empty init() method to setup the param hierarchy during the query time such
that the lookup chain becomes - local params, then qparser init params and
then request params. It is along similar lines to Eric's suggestion. But I
am not sure if we want to create a custom parser for this or make it a
general behavior..
