title: Firebase firestore subcollection ordering and limit
body: <p>I have a subcollection with the path of <code>/coll_A/document_A/coll_B</code>, where coll_A/_B - are collections. I want to query this subcollection with ordering and limit:</p>
  
  <pre><code>firestore.collection("coll_A")
          .document("document_A")
          .collection("coll_B")
          .orderBy("time", DESCENDING)
          .limit(10)
          .get()
          .addOnCompleteListener(...)
  </code></pre>
  
  <p>But it always returns the full collection. What am I doing wrong?</p>
  
  <p><code>time</code> is a number timestamp.</p>
  
  <p><strong>Upd</strong>.: <code>time</code> is just an example, I used an integer field before. As per answer from Alex Mamo, it should be able to order by it.</p>
  
  <p><strong>Upd. 2</strong> I tried to prepare a screenshot and removed and re-added the data - and it started to work. Data is all the same, collection-doc-collection hierarchy also, so probably some kind of a glitch.</p>
