How to search in multiple nodes in Firebase Database?

//Initialize variable
        currentUser = mAuth.getCurrentUser();

        if(currentUser != null) {
            final String uid = currentUser.getUid();

            FirebaseDatabase firebaseDatabase = FirebaseDatabase.getInstance();
            DatabaseReference databaseReference = firebaseDatabase.getReference().child("count");
            Query query = databaseReference.orderByChild(uid).equalTo(uid);

            ValueEventListener valueEventListener = new ValueEventListener() {
                @Override
                public void onDataChange(DataSnapshot dataSnapshot) {
                    //test for null and validity
                    if(dataSnapshot.exists() && dataSnapshot.getValue()!= null) {

                        for(DataSnapshot ds : dataSnapshot.getChildren()) {
                            String totalRCount = Objects.requireNonNull(ds.child("total_recycled_count").getValue()).toString();

                            //set totalRecycledCount in a profile textview
                            profile_totalrecycledcount.setText(totalRCount);

                            DatabaseReference uidRef = firebaseDatabase.getReference().child("users").child(uid);
                            ValueEventListener eventListener = new ValueEventListener() {
                                @Override
                                public void onDataChange(DataSnapshot dataSnapshot) {
                                    String name = dataSnapshot.child("name").getValue(String.class);
                                    String email = dataSnapshot.child("email").getValue(String.class);
                                    Log.d("TAG", name + " / " + email);

                                    //set profile in result textviews
                                    //Don't forget to initialize your profile_name and profile_email and get their xml reference, which is not shown in this code.
                                    profile_name.setText(name);
                                    profile_email.setText(email);

                                 }

                                @Override
                                public void onCancelled(@NonNull DatabaseError databaseError) {}
                            };
                            uidRef.addListenerForSingleValueEvent(eventListener);
                        }
                    }
                }

                @Override
                public void onCancelled(@NonNull DatabaseError databaseError) {}
            };
            databaseReference.addListenerForSingleValueEvent(valueEventListener);
        }
