title: How to the get the Wordpress Media Search to include tags?
body: <p>I've added tags to all Media items with this code:</p>
  
  <pre><code>function wptp_add_tags_to_attachments() {
      register_taxonomy_for_object_type( 'post_tag', 'attachment' );
  }
  add_action( 'init' , 'wptp_add_tags_to_attachments' );
  </code></pre>
  
  <p>It works great expect one thing. If I search for a media file in the Admin Media Library it does not work with tags. </p>
  
  <p>How can I get the Admin Media Library to include the tags in the search?</p>
