Search
Engines
Most
students tend to rely only on Google for searching the Internet.
However it is best to develop skills in using other search engines.
There are many search engines available; the following is a small
selection.
Google
Perhaps
the most popular keyword search engine used in schools. Google
provides quick and reliable results.
AltaVista
AltaVista
or “a view from above” is a keyword search engine
that has the advantage of searching for video and MP3/Audio.
Yahoo
Yahoo
is a directory search engine that is good for broad category searches
and where an overview of a topic is required.
Meta-Search
Engines
In a meta-search
engine, you submit keywords in its search box, and it transmits
your search simultaneously to several individual search engines
and their databases of web pages. Within a few seconds, you get
back results from all the search engines queried. Meta-search
engines do not own a database of Web pages; they send your search
terms to the databases maintained by search engine companies.
Some meta-search engines are:
Dogpile
Dogpile
puts the power of all the leading search engines together in one
search box to deliver the best combined results. The process is
more efficient and yields more relevant results. Other meta-search
engines include Metasearch and MetaCrawler. They use meta-search
technology to search the Internet's top search engines, including
Google, Yahoo! Search, MSN Search, Ask, About, MIVA, LookSmart
and more.

Clustered
Search Engines
A clustered
meta-search engine presents the results in clusters. They have
the advantage of refining the search results for you so selecting
the results you need is made easier. Some examples include:
Clusty
Clusty

generates an ordered list based on comparative ranking. This meta-search
approach helps raise the best results to the top and push search
engine spam to the bottom.
Mooter

presents its search results as a mind map cluster.
