Hotbot.com engine

HotBot is one of the early Internet search engines and was launched in May 1996 as a service of Wired Magazine. It was launched using a "new links" strategy of marketing, claiming to update its search database more often than its competitors. It also offered free webpage hosting, but only for a short time, and it was taken down without any notice to its users. Though competitive when it was acquired by Lycos in 1998, HotBot has in recent years reduced its scope. Today the website is merely a front end for third-party search engines Yahoo.com, and MSN, as well as Lycos' own lyGo.com. It was one of the first search engines to offer the ability to search within search results. The site still exists, however it is run by Yahoo! mainly.

HotBot, owned by Lycos, allows you to search using Google, MSN and Ask.com. Enter in your search terms and select the search engine you want to use. You can then switch between search engines to see how the results differ.
