Subject [jira] [Comment Edited] (SOLR-3177) Excluding tagged filter in StatsComponent

This would indeed be useful. The only alternative I see now besides having a static min and
max, is firing two queries; one with and one without the fq for the price slider.

It seems to me that a large part of the code from solr.request.SimpleFacets beyond this line
can be re-used in solr.handler.component.StatsComponent. (Too bad I'm not capable enough...)
{code:java}
// figure out if we need a new base DocSet
    String excludeStr = localParams.get(CommonParams.EXCLUDE);
    if (excludeStr == null) return;
{code}

> 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}
