title: Determining how many results are shown by ng-repeat filter
body: <p>If I use <code>ng-repeat</code> with <code>filter</code>, how can I determine how many elements are filtered out (or vice versa, how many are shown)? Specifically, I would like to create a search bar that creates the filter, but I would also like to show how many elements are hidden by the filter (ie something like <code>Showing 6 of 10 results</code>).</p>
