Search Engines
Search engines are handy tools that help you find what you want on the Web. Each search engine uses software (called spiders or robots) to compile a database of pages found on the publicly accessible Web. Each search engine searches the part of the Web it has collected --not the whole Web--and each search engine has a somewhat different database.
There are two types of search engines.
| Search Engines | MetaSearch Engines |
|
Google is an example of a search engine. When you enter your search in a search engine, it searches within its own database of web pages for the keywords you enter, wherever they appear on a Web page. Other search engines: AlltheWeb, Hotbot, Excite, Yahoo, and USA.Gov |
Ixquick is an example of a metasearch engine. Metasearch engines search the databases of several search engines at a time. Most eliminate duplicate listings, however, you usually have little control over search options. Other metasearch engines: Dogpile, Mamma, and MetaCrawler. |
