title: Firebase querying data
body: <pre><code>{
    "random_key 1" : {
      "id": 0,
      "text": "This is text"
    },
    "random_key 2" : {
      "id": 1,
      "text": "This is text"
    }
  }
  </code></pre>
  
  <p>If I'm storing my data like this, and I want to get the node where <code>id</code> is equal to <code>0</code>. How can I do that?</p>
  
  <p>The above is the child of <code>issue</code>, which is a child of <code>root</code>.</p>
