Multi-value indexes
Example, I want to paginate through high priority records in a table. Priority is a number, and high priority is anything above 10. I either have to do excess pagination calls on the frontend to build up a page, or add a "high priority" field to the table that provides a boolean for whether the priority field qualifies as "high".
I don't honestly know what the API for that would look like. Maybe each field name string in the index definition can be optionally replaced with a config object.
