Search SharePoint content from Windows 7
Windows 7 has a feature called “Federated Search” that allows you to search other content sources through windows explorer. This works with SharePoint and is pretty easy to setup.
How to create your own search
1. Create a text file that contains the following XML, modify everything in double brackets [[ ]] to meet your needs (be sure to remove the brackets also).
2. Save the file and change the extension to .osdx
3. Double click your new .osdx file and Windows will ask if you want to save the search.
4. The search should appear in the left pane of Windows Explorer. Just click on it to do a search.
