Let's say that I have a facet named 'subject' that contains one of: physics, chemistry, psychology, mathematics, etc....
I'd like to do a search for the top 5 documents in each category. I can do this with a separate search for each facet, but it seems like there would a way to combine the search. Is there a way? That is, if the user searches for "my search", I can now search for it with the facet of "physics" and rows=5, then do a separate search with the facet of "chemistry", etc... Can I do that in one search to decrease the load on the server? Or, when I do the first search, will the results be cached, so that the rest of the searches are pretty cheap?
