A look at 7 Windows 7 federated search connectors
Windows 7 supports a new feature called Federated Search. It's based on OpenSearch and RSS2 and enables searching of remote repositories from the Windows desktop. Microsoft embracing Open initiatives? Might there be some less-than-altruistic motivation behind this?
Better desktop searching may mean less browser-based searching, which might allow Microsoft to gain a little ground on Google. Still, the ease of creating connectors and the number of possibilties add some serious cool factor to Windows 7. They're a bit hard to find as of yet, but the popularity of the Windows 7 Beta torrent will no doubt lead to some new ones being created in the coming weeks.
The first one I encountered when running build 6801 was Long Zheng's Flickr Connectr. Though it's a man-in-the-middle solution and slightly slow at times it works well, and you can see it in action in the screen capture above. Image results can be displayed just like other files on your desktop - in list or details view, as thumbnails, or using Windows 7's content view.
Windows 7 Forums has several useful connectors for download, including YouTube, Yahoo, Live Search, Google News, and Google Blogs.
Brandon Paddock of Brandonlive.com has created a connector for DeviantArt. I wasn't able to find the download link on his blog, but you can still download it directly.
