How to create an index on a child property of an array object in Firebase

Question

In my firebase app I am storing objects in an array structure using the push() method that generates unique ids. These objects have a child property called \"scheduledDate\"

Answer 1

This should work:

{
  "rules": {
    "events":{
      ".read" : "auth != null",
      ".write" : "auth != null",
      "$uid": {
        ".indexOn": "scheduledDate"
      }
    } 
  }
}
