Firestore Query Across Multiple Fields for Same Value

Question

Is it possible to query multiple fields in a firestore document for the same value?

Imagine I have numerous documents where each described a sport:

s         


        

Answer 1

One way to do something like that would be to restructure your data like so:

["bowling" : [
"ball": true, "bowling alley": true, "bowling shoes": true,
"description": "bowl the ball" ]]

and then query for documents where "ball" is equal to true:

Firestore.firestore().collection("sports").whereField("ball", isEqualTo: true)
