Official Google Blog: Blog search and beyond
Since google launched the Custom Search AJAX gadget for Blogger on our experimental site, we've gotten some great feedback. Now, the tuned-up search gadget is available to all Blogger users. You can configure this gadget to help your readers search all the information that's relevant to your blog — your posts, webpages that you link to, and sites that you link to from the sidebar — all in one shot. When your readers search using this gadget, the results are displayed with the look and feel of your blog. And they show up inline, so readers don't have to leave your blog. After they're done, they can quickly dismiss the results and go back to reading your blog posts. Take a look at how S. Krishna's Books uses the gadget.
