Hi Clare,
The fastest way to do this would be to run the query multiple times.
So for your "sport" example you'd do something like this;
fishing_count = index.search_each("sport AND fishing", :num_docs => 1) {}
shooting_count = index.search_each("sport AND shooting", :num_docs => 1) {}
# etc.
Then go ahead and paginate your query as you usually would.

Quite possibly. But running the query multiple times should be fine in
terms of performance. You could use filters instead of the code I
demonstrated above to further improve performance.

I'm not exactly sure what you mean here when you say "would this be
called through ruby". I hope I've already answered your question. Let
me know if I didn't.
Cheers,
