How search engines work

How search engines work

Search engines are designed to find information on the Internet.  'Bots' or 'spiders' seek out pages on the Internet and index them, so that when you do a search you are able to find them.

More Google search tips from Daniel Russell, a research scientist at Google:


Not everything on the Internet is available through a search engine.

Many web pages, such as the Library's article databases, are excluded from most search engines due to licensing restrictions. This excluded material is referred to as the "Invisible Web" -- what you don't see in search engine results.

When you are searching for information on your research topic, besides using Google, take advantage of the Library's multiple databases to find scholarly books and articles on your topic that you will not find on the open Internet. 

Other search engines

Google is not the only search engine worth exploring if you are trying to find information on the Internet.  There are search engines dedicated to specific formats, like searching blogs and multimedia.

Give it a try!
