What is a search engine?
An Internet tool that:– created by computer programs– searches for sites that contain the keyword(s) you
provide– allows you to search by words or phrases– matches your request against a database– provides results in the form of links to sites– examples include Alta Vista, Infoseek and
WebCrawler
What is a subject directory?
An Internet tool that:– created by a person– organizes sites by subject– allows you to browse through lists of sites by
subject or topic– provides results by narrowing searches using
lists of descriptors– examples include Yahoo, Excite and Magellan

Subject Directory

How do you narrow a search?
Linking search terms with the word AND narrows your search – example: heart AND attack
Only provides links to sites with both terms Ignores sites with just one term Using AND more than once further narrows a
search– example: heart AND attack AND prevention
How do you broaden a search? Linking search terms with the word OR
broadens your search – example: aging OR elderly
Provides links to sites with either term Useful when several words are
interchangeable Using OR more than once further broadens a
search– example: aging OR elderly OR seniors
What are other searching tips?
Other terms that limit or narrow your search NOT, NEAR, WITH, AND NOT
Case sensitivity Use of quotation marks Read tips on search engine home page Use of parentheses
What is a “wild card”
