Usage: using Distributed Desktop Search is as simple as a classical p2p client! When you launch DDS for the first time, it behaves just like a classical Limewire (Gnutella) client. If you want to enable the content-sharing feature, simply go to the Tools/Options/Content Sharing menu (see screenshot) and select the indexing application you want to use. You can choose between a custom application bundled with DDS or Google Desktop Search (in this case you must install it before).
