Yahoo UK has launched Search Suggest at Yahoo Search for UK users. If you do not see it now, you will probably see it in the “coming days,” a Yahoo representative told me.
When you begin to type a keyword, Yahoo will now offer their UK users suggestions. I covered the US launch of search suggestion back on July 12th.
Yahoo has also been beta testing Search Assist, which I happen to now see as of this morning. Search Suggestions On Steroids: Yahoo Search Assist from Danny Sullivan a while back showed off many of the features of this new beta interface. I am personally able to see it in New York, but I asked other people in the US if they can see it, and they were not able to.
