Firebase endAt() method don't work with FirebaseListAdapter

I want to display all result, where field "userGood" ending with "true". I am use next code in FirebaseListAdapter.

FirebaseListAdapter<User> firebaseSuccessfulTaskListAdapter = new FirebaseListAdapter<User>(
                this, User.class,
                R.layout.item_user,
                FirebaseDatabase.getInstance().getReference()
                      .child("users").orderByChild("userGood").endAt("true")){

      @Override
      protected void populateView(View v, Task model, int position) { }
};

Data structure: 

{
    "users": {
        "1": {
            "name": "bob",
            "userGood": "bob_true"
        },
        "2": {
            "name": "max",
            "userGood": "max_false"
        },
        "3": {
            "name": "mike",
            "userGood": "mike_true"
        },
        "4": {
            "name": "bob",
            "userGood": "bob_false"
        }
      }  
     }

When i use this code, they display to me all data with my database. Can you help me how to fix it? Thanks!

The function is endAt, not endWith. You're getting everything that comes before "true" alphabetically. The Firebase API does not support partial text matching. Either look into a third-party text search solution like ElasticSearch/Flashlight, or refactor your data model so that your queries can be made using the built-in functions. For example, why can't userGood just be a Boolean true or false?
