I'm using Firebase Firestore. How to correctly write a query so as not to return some of the lines from the document? For example, don't return the created_at
field. There is a variation of all fields that do not need to be returned to hide in the subdocument. But then how, in the future, can you make a request using a condition if the field by which you need to form a condition is in a subdocument?
PS: Fields should not appear at the user level.
