Retrieve only some params from a node at Firebase (web)?

Does firebase allows me to fetch only some params from a node ?

Example User has: id, name, email, birthday, zip_code

But I only want id and name for an specific search.

To get users list at web app I can do:

var database = firebase.database();
return firebase.database().ref('/users).once('value').then(function(snapshot) {
  console.log('list de users: ');
  console.log(snapshot.val());
});

But this retrieves all users params, how can I get only id and name from /users at Firebase?
