from 1,675,00+ down to 50 or less.
The Major Search Engines
AltaVista
AltaVista is one of the oldest crawler-based search engines on
the web. It has a large index of web
pages and a wide range of power searching commands. It also offers
news search, shopping search and
multimedia search. AltaVista opened in December 1995. It was
owned by Digital, then run by Compaq
(which purchased Digital in 1998), then spun off into a separate
company which is now controlled by
CMGI.
Ask Jeeves
Ask Jeeves is a human-powered search service that aims to direct
you to the exact page that answers
your question.
Excite
Excite offers a medium-sized crawler-based web page index, as
well as access to human-powered
directory results from LookSmart. Excite was launched in late
1995. It grew quickly in prominence and
consumed two of its competitors, Magellan in July 1996, and WebCrawler
in November 1996.
Magellan was discontinued in April 2001. WebCrawler continues
to operate as a separate service, but it
provides the same results at the Excite.com site itself.
Google
Google is a top choice for web searchers. It offers the largest
collection of web pages of any
crawler-based search engine. Google makes heavy use of link analysis
as a primary way to rank these
pages. This can be especially helpful in finding good sites in
response to general searches such as
"cars" and "travel," because users across
the web have in essence voted for good sites by linking to
them. The system works so well that Google has gained wide-spread
praise for its high relevancy.
Google provides web page search results to a variety of partners,
including Yahoo and Netscape Search
(see below). Google also provides the ability to search for images,
through Usenet discussions and its
own version of the Open Directory (see below).
HotBot
HotBot is a favorite among researchers due to its many power
searching features. In most cases,
HotBot's first page of results comes from the Direct Hit service
(see above), and then secondary results
come from the Inktomi search engine, which is also used by other
services. It gets its directory
information from the Open Directory project (see below). HotBot
launched in May 1996 as Wired
Digital's entry into the search engine market. Lycos purchased
Wired Digital in October 1998 and
continues to run HotBot as a separate search service.

Design Simulation Demo
If you are looking for gold, you have come to the right place.
Here, we let you dig for gold effortlessly, and we guarantee
maximum profit. To simulate your gold-digging expedition, you
are provided with a two-dimensional cross-section of earth in
which you draw the gold ore deposits with the mouse. Then, based
on parameters that you've specified for the cost of excavation
and the value of gold, RIOT will automatically determine where
you should spend your time digging!
