Search Engines Information Skills Group 4 Jera Alcorn, Tambra Scroggins Keri Tarpley, Melain Blackwell 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. Comparing search engines A variety of search engines were used to perform a search on "The French Revolution". The following slides provide detail on the search results as well as the search engines features. Many search engines rely on the results of other search engines.

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.
