Everyone exhibits "your search for x has returned y results" on the top
of the results page, but we need something else, which would be
something like "your search for x returned y results in z records",
being z the numdocs of the SOLR response and y a SUM(quantity) of all
returned records.
In SQL you can do something like:
SELECT count(1), sum(quantity) FROM table
But with SOLR we don't know how can we do the same without having to
return all the XML result for the field "quantity" and then sum it to
show the total. Any hints on how to do it in a better way?
cheers,
