* Optimize pagination, removing offset
* For search, don't add `where` clause for empty queries
* Revert "Replace `COUNT(DISTINCT primary_key)` with `COUNT(*)`"
Genres are required as part of the count queries, so filter by genres work
* Optimize search3 query, using order by id if it is a "" query.
Also fix the optimizePagination query logic
* Allow offset optimizer threshold to be configured
