LYCOS.COM is powered by FAST, FAST powers AllTheWeb. Lycos uses the same database as AllTheWeb. I think the people at Lycos can make some changes to the Algo so they show slightly different results than you see on AllTheWeb.com You don't need to pay to get included in Lycos. You only need to submit to AllTheWeb. Lycos have there "Free submission" [searchservices.lycos.com...] (At the right) After you've field it in it goes to FAST.
Mac - on lycos.com any searches containing accented or other extended (i.e. non-ASCII) characters fail to produce results. IT'S A BUG! This bug sadly lives on their site for some weeks now http://www.webmasterworld.com/forum4/430.htm [webmasterworld.com]
>vary big time depending on wich Lycos you query apart from that bug the FAST delivered results are identical on all Lycos sites - IF the search options are set to worldwide.
