firebase - Firestore order by two fields

Question

In firestore I'm wondering if there is a way to have a hueristic1 and get all data between two hueristic1 values but order the results based on a hueristic2.

I ask because the data at bottom of both pages

https://firebase.google.com/docs/firestore/query-data/order-limit-data

https://firebase.google.com/docs/firestore/query-data/query-cursors

there seems to be slightly contradictory documentation.

What I want to be able to do is

Ref.startAt(some h1 value).endAt(some second h1 value).orderBy(h2).  

I know I'd probably have to index by h1 but even then I'm not sure if there is a way to do this.
