Search Engines
The search engines listed here represent a small portion of the
total number available. Remember no one search engine covers all
the web. Overlap studies show that about half the pages covered
in any one search engine database exist only in that database. So,
if you don't find what you are looking for with one,
try another.
The Biggest Search Engines:
These search engines cover between one billion and two billion
pages.
-
AlltheWeb - Motto is "find it all" and it comes in
close to Google in number of pages indexed. Allows you to limit your search to
news, pictures, video, audio or ftp files. Allows you to search in 49 different
languages. This is a pure search engine and does not include any extra features
such as directory or personals or news links.
-
Alta Vista - Allows you to limit
your search to images, news, audio or video. The only language option is Spanish.
It as not as pure a search engine as Alltheweb or Google. In addition to a
directory there are links to weather, shopping, personals, and travel sites. In
number of pages covered it is smaller than either Google or Alltheweb.
-
Google - Allows
you to limit your search to images or news. One special search option is the
ability to search Usenet news groups. Also allows you choose one of several
different languages. There is a search directory, but no other features.
-
Teoma - Motto
is "search with authority." Claims to use a revolutionary approach to
give the most relevant results. A pure search engine, there are no extra
features. It is a new search engine and search options are limited. For example,
you cannot search by file type and you are limited to a choice of ten
languages.
Other Search Engines:
These search engines are smaller in coverage than the four
listed above. With these, however, there are number of extra
features such as news, weather, personals, email, sports, games
and movies.
Meta-Search Engines - Also
known as multiple or mega-search engines. A meta-search engine
searches several single-search engines at once.
