title: Firebase queryOrderedByChild in descending order
body: <p>In Firebase is there a way to get query in descending order using <code>queryOrderedByChild</code>. I want to get limited data without getting whole snapshot. I have use <code>queryEndingAtValue</code> and <code>queryLimitedToLast</code> together. However I want to get query in descending order using <code>queryOrderedByChild</code>. Is there a way to do this in Firebase?</p>
