Would the downvoters kindly explain themselves? I intended to pose an honest question about how they're doing autocomplete. Apparently I'm the only one who hasn't seen that particular behavior on a search engine before. I don't recall that specific set of suggestions show up in any other search box I've used, probably because I don't pay attention.

Edit: I see now that I misinterpreted the parent. I thought he meant those just happened to be the top Lycos search terms, but he meant that the name of the form element was shared with other sites that have search fields I use.

I don't think you understand. Try using it in incognito mode. It even works there. Try clearing your browser form history. Now it doesn't.
