Lycos

    A web index, served by Carnegie
   Mellon University.  It allows you to search on document title
   and content for a list of keywords.  Lycos is probably the
   biggest such index on the web.  By April 1995, the Lycos
   database contained 2.95 million unique documents.

   The Lycos database is built by a Web crawler that can bring
   in 5000 documents per day.  The index searches document title,
   headings, links, and keywords it locates in these documents.

   The Lycos servers are efficient but overloaded.  Failure to
   connect or "please try later" messages are common.
