title: Apply a filter on FirebaseRecyclerAdapter
body: <p>I am using <code>FirebaseRecyclerAdapter</code> to display chat messages.</p>
  
  <pre><code>private void attachRecyclerViewAdapter() {
      lastFifty = mChatRef.limitToLast(50).;
      mRecyclerViewAdapter = new FirebaseRecyclerAdapter&lt;Chat, ChatHolder&gt;(
              Chat.class, R.layout.message, ChatHolder.class, lastFifty) {
  
          @Override
          public void populateViewHolder(ChatHolder chatView, Chat chat, int position) {
              chatView.setName(chat.getName());
              chatView.setText(chat.getText());
              chatView.setTimeLocation(chat.getTime());
              FirebaseUser currentUser = mAuth.getCurrentUser();
  
              if (currentUser != null &amp;&amp; chat.getUid().equals(currentUser.getUid())) {
                  chatView.setIsSender(true);
              } else {
                  chatView.setIsSender(false);
              }
          }
      };
  </code></pre>
  
  <p>I have a list that contains list of specific users. I would like to apply filter to see only messages from those specific users. What should I do ?</p>
