Perform a second query to find total search count
This removes the need for SQL_CALC_FOUND_ROWS which can really slow down
queries in a lot of cases. The COUNT(*) query we end up performing can
reuse a lot of the original clauses from our primary query, but we can
really slim it up by omitting some joins and the sorting/limiting
clauses.
