Does Chrome's search give you realtime term completion? If you start typing in the search box on Wikipedia, it will give you suggestions that are the titles of articles. It's a substantial usability improvement over just typing something, since it gives you the opportunity to skip directly to a page more often, rather than going through the vigorously mediocre search results page.
Huh. Maybe I need to update Chrome, because it's not working for me. Weird.
EDIT: It was just a hiccup when I checked; the problem is gone now. Thank you for pointing that out; from now on I'll use this method to search Wikipedia.
