During the Keynote at TechEd we showed Federated Search Connectors for Windows 7 Windows Explorer.   I have been using this for searching the web using Bing!  I have just uploaded the Search Connector for Bing! to my Sample Code page.

To use it simply;

• create a new folder on your C: drive “Search Connectors”
• download the Bing.osdx file to this new folder
• double click the Bing.osdx file
• click Install, then you are ready to go

You can also create Federated Search Connectors to other OpenSearch standard search services such as Flickr and YouTube or you could even create one for SharePoint.
