What type of search engine should
            you use?
The type of search engine used depends on the
information one is looking for. There are various
search engines available. There are also visible and
invisible searches. Search engines allow one to use
a very broad search, or narrow the search by using
techniques such as Boolean.
 Visible and Invisible Searching
The Visible Web: includes the search results of a web inquiry
or web directory; i.e. Google search will yield search results
from the visible web.

The Invisible Web: is composed of full-text, statistical
databases, online multi-media resources, online journals, and
government documents. EbscoHost and ProQuest are both
examples of invisible web resources. Access to many of the
invisible web resources are reliant on additional web portals
and subscriptions.

Generally, the invisible web searches yield more scholarly and
reliable sources when compared to the results of visible web
searches.

A variety of search engines were used to perform a
search on "The French Revolution". The following

   The key to an effective search for information begins with
knowing the "right" questions to ask. A good place to start is by
using the visible web, with such search engines as Google. Using
meta search engines, such as dog pile, may tend to prove
redundant. Progressing through a query, using Boolean logic,
will help to navigate one through the sea of
information. Continuing a search often leads one through the
invisible web to databases such as EbscoHost.
