Lycos

Lycos is one of the oldest search engines on the Internet
today, next to Altavista and Yahoo. Their spider, named
"T-Rex", crawls the web and provides updates to the Lycos
index from time to time. The FAST crawler provides results
for Lycos in addition to its own database.

The Lycos crawler does not weigh META tags to heavily,
instead it relies on its own ranking algorithm to rank pages
returned in results. The URL, META title, text headings, and
word frequency are just a few of the methods Lycos uses to
rank pages. Lycos does support pages with Frame content.
However, any page that isn't at least 75 words in content is
not indexed.
