The specifics of your overall goal confuse me a bit, but drilling down to your core question...
: I want to be able to use the dismax parser to search on both terms : (assigning slops and tie breaks). I take it the 'fq' is a candidate for : this,but can I add dismax capabilities to fq as well? Also my query would be ...you can use any parser you want for fq, using the localparams syntax... http://wiki.apache.org/solr/LocalParams ..so you could have something like... q=foo:bar&fq={!dismax qf='yak zak'}baz ..the one thing you have to watch out for when using localparams and dismax is that the outer params are inherited by the inner params by default -- so if you are using dismax for your main query 'q' (with defType) and you have global params for qf, pf, bq, etc... those are inherited by your fq={!dismax} query unless you override them with local params -Hoss
