title: Get users by name property using Firebase
body: <p>I'm trying to create an application where I can get/set data in specific users accounts and I was tempted by Firebase.</p>
  
  <p>The problem I'm having is that I don't know how to target specific users data when my structure looks like this: </p>
  
  <p><img src="https://i.stack.imgur.com/eQmWu.png" alt="My data structure described by the text below."></p>
  
  <pre><code>online-b-cards
    - users
      - InnROTBVv6FznK81k3m
         - email: "hello@hello"
         - main:  "Hello world this is a text"
         - name:  "Alex"
         - phone: 12912912
  </code></pre>
  
  <p>I've looked around and I can't really find anything on how to access individual data let alone when they're given some random hash as their ID.</p>
  
  <p>How would I go about grabbing individual user information based of their name? If there is a better way of doing this please tell me!</p>
