Do we have tests which combine compartment search with DateTime comparison? Is that even possible?

There shouldn't be any restriction on multiple rewriters being used. I thought I there was a case in the Patient Everything tests, but I wasn't able to get both rewriters to fire

I noticed we are still storing the compartment indices in the Cosmos DB resources - is this intentional?

Good question, happy to null them out first if it feels like the right thing to do. Since this doesn't apply to SQL yet, it might make sense to remove all this code with that as a second part. Also, if we were forced to roll-back for any reason, I'd rather still have them there :)
