Querying a list in Firebase Firestore

I am using Firebase Firestore database in my project. I have a data structure as below:

I need to write a query which finds the users with a specific person in the following people part of the document fields.

For example if I query for the users which following person0 both user1 and user2 will be returned according to my example above.

Any suggestion will be appreciated.

Storing the followingPeople in an array is an anti-pattern. Please read the Firestore documentation on working with arrays, lists and sets for a better approach.

followingPeople: {
    "person0": true,
    "person1": true,
    "person2": true
}

I'd also recommend reading my answer to http://stackoverflow.com/questions/40656589/firebase-query-if-child-of-child-contains-a-value. While it was written for the Firebase Realtime Database, the same logic applies here.
