Is there a way to search for a specific user among the millions of users in Firebase, for example, by his name or phone number for his observation, so that I can look at all his other data
So you want to create some kind of spyware? I don’t think this is legal.
I think you are going wrong here he wants to get his app’s user data by his username which i think every app developer gets
Maybe Jihed can clear this out. He wrote about 1 million users of firebase and I can’t believe that he has an app with one million users.

Yes, this is exactly what I want to do.
What is the problem that the application reaches a million users, is this a problem!!?
I’m already getting my app’s users data already. But I can’t search for a specific user among the thousands
Now that I have corrected the point of view, is there a solution?
You should use Firebase indexing and searching features for such a task, on Firebase, probably introducing cloud functions to your Firebase project with the Firebase CLI. I would recommend you read up on how Firebase can help you to achieve this. There is a wide range of documentation, and many videos. You might also want to consider using Firestore instead of Realtime Database for a project/app that will have 1m+ users, and get a good understanding of data flows in order to manage your costs - which could be significant with those numbers…

My dream is to have this kind of problem.
i can only imagine how much is spent with billing 
In your case I would recomend you to hire a specialist in firebase, because the way you organize and search your database will probably have a significant impact on your billing.
I haven’t downloaded my app in the play store yet, so I want to clean everything up before downloading.how much Does it cost a million users on firebase
Oh yes

Complain to Google about the prices. Mark Tim’s answer as the solution and don’t go off-topic.
MySQL is better thhan Firebase, so it’s better to get into it and learn it and you can easily use it however you want in your app

Of course, if you can search in Firebase, it is the number of users you have (+ 1 million), I have a method but it has a cost if there is someone interested
@christian_cesar_quil
What is the method I am interested?
I hope there is no easy method rather than the one which i hava suggested in post 2
It will not take the whole tag list. IF you are looking for such method, then you do have to pay more and more as you said in earlier post…
@Still-learning
I was looking forward to your method but I didn’t understand it well
Please can you help me search in firebase I was interested in your post but you deleted it
