Really a directory, rather than a search engine. Owned by the same folk as Excite and Webcrawler . It takes your information, runs it through WebCrawler, InfoSeek, AltaVista, Lycos, Excite, and Yahoo, then compiles and presents the results. There are specialty lookup pages like Search. It changes the search.
Lower case is usually safest.
For fun, you can watch other people search at Search Voyeur or MetaSpy . Bonuses are also given if words are close together or appear multiple times. InfoSeek lets you search the web, usenet, email addresses, and news services. Excite will search for people, email, yellow pages, and newsgroups as well as the web.
