There are two new tokens in the token list for Search Directory.  Below is an example using the new [MEDIATYPE] and [GROUP] tokens.

By adding the Media Type token in the List template, an icon will be displayed for the appropriate media type - audio, video, image, or application.  This example is of a video.

The Group token will display the item's group.  The item's group is assigned when the item is added via Index Item.  Note: The token displays just the group name.  The "Group:" text that precedes the group name was added to the template in this example.  This is how it looks in the template sans quotation marks - "Group: [GROUP]"
