> It would be useful to exclude the effects of some "fq" params from the set of documents used to compute stats -- similar to 
> how you can exclude tagged filters when generating facet counts... 
> https://wiki.apache.org/solr/SimpleFacetParameters#Tagging_and_excluding_Filters
> So that it's possible to do something like this... 
> http://localhost:8983/solr/select?fq={!tag=priceFilter}price:[1 TO 20]q=*:*&stats=true&stats.field={!ex=priceFilter}price 
> If you want to create a price slider this is very useful because then you can filter the price ([1 TO 20) and nevertheless get the lower and upper bound of the unfiltered price (min=0, max=100):
> {noformat}
> |<-[-------]-------------->|
> $0 $1     $20            $100
> {noformat}
