javascript - Firebase search by child value

Question

I have the following structure on my Firebase database:

I would like to search for an user by name, last name or email but as I don't have the user key in the level above I don't know how I can achieve this. I'm doing and administrator session so it wouldn't have access to the user key.

I have tried:

let usersRef = firebase.database().ref('users');
usersRef.orderByValue().on("value", function(snapshot) {
    console.log(snapshot.val());
    snapshot.forEach(function(data) {
        console.log(data.key);
    });
});

But it brings all the users on the database. Any ideas?
