* no changes

-----------------------------------------
* Disallow literal-only expressions
* Allow count for boolean expressions

-----------------------------------------
* Add caching for total_count

-----------------------------------------
* Allow nested operators and values within an in operator
* "notin" filter operator is refactored to not use separate code from in. Instead we generate the in code and then
