if you scroll down:

citiesRef.where("population", ">", 100000).orderBy("country")

is invalid...

EDIT: sorry got confused & posted wrong example (population/population vs population / country)

That is interesting. The examples show this limitation.

> Invalid: Range filter and first orderBy on different fields

But I can’t find any documentation on what exactly the limitations on orderBy are.

The reference docs on queries don’t mention any limitations on order_by: https://cloud.google.com/firestore/docs/reference/rpc/google...
