I want all search in the same interface. I should be able to send a search query to an IM buddy and it search Google (okay, so that bit's done), eg "wsdl yahoogroups" which using the cleverness of I Feel Lucky gives me the homepage of the WSDL mail list. Now when I type "binding -soap" in the same IM interface it should use that query to search the WSDL Yahoogroup archives, using the search engine attached to that page. My knowledge of where best to search, plus consistent UI.
