When searching for paid apps, some SQL queries are made because the data is not in ES. We should find a way to move everything to ES at some point, but in the meantime we can at least reduce the number of SQL queries made.
Fixed in https://github.com/mozilla/zamboni/commit/e4f6d8f941b9f16b20bb9109a62d1b7fcf4c5b84 QA: - Make sure searching for paid apps and displaying their price still works correctly (including region exclusions, price depending on locale)
Verified as fixed in mp-dev and mp-stage in FF42(win7) Searching paid apps works, prices are displayed correctly etc. Closing bug.
