Shashi Seth runs Google Co-op, which is a set of services that let you build your own custom search engine and add that to your blog or site. What’s cool about that? Well, you could add a search box to your site that lets your users just search your site’s info, or just search your friend’s sites. We sit down and learn more about that, and get a good demo of how you can do it on your own site. You can see the custom search engine in action on Shashi’s own blog (about wine): http://grapejooz.blogspot.com.
