A while back I was playing around with developing Chrome extensions and very quickly hashed up one to search the European Bioinformatics Institute's web site. It works by providing a context menu item when you select some text on the page. It also works in the omnibox: if you type "EBI" before your search term you will be taken directly to the search engine.
I have attached the extension here for posterity.
