We just released the Ecto search function. It searches the local Ecto libarary for content, pages and groups. In addition it searches youTube and Flickr and we also created an easy jump to do a Google, Yahoo!, MSN and Wikipedia search as well.
The best part is that if you are accessing the search from a learning page that you are creating you can add the content into your page with one click.
Try it out, it is pretty cool!
