Custom Search Engine that automatically knows what to site restrict

I have been waiting for this for awhile. You can now create the list of sites for a custom search engine on the fly.

This search below should search through my blogroll on the left (which I never update but that is another issue to do with me not generating the list from my opml feed like I should).








E.g. search for something like 'gears'. How it does this on the fly is quite impressive.
