title: Get collections in subcollections and subcollections
body: <p>I have a problem with the firestore. The problem is that I have such a database. And I'd like to download all the stuff in the hives collection. The problem is that there are different collections for each of the apiaries. I have, for example: 3 documents in apiaries and for each apiaries and in each document I have, for example: 5 hives. And I would like all the details from all the hives.</p>
  <pre><code>users:
    {uid}:
      apiaries:
        {uid}:
          hives:
            {uid}
      notes:
        {uid}
  </code></pre>
