SECTION 3: USING SEARCH ENGINES EFFECTIVELY

DIFFERENT KINDS OF SEARCH ENGINES

We use the term search engine generically to describe ALL Web search tools. But, there are different kinds of search tools or search engines:

TRUE search engines -- whose databases are built by computers.

WEB DIRECTORIES -- whose databases are built by people.

HYBRIDS -- search engines that are part Engine, part Directory.

META search engines -- one search tool that searches up to 10 other search engines at one time.

MEDICAL or HEALTH CARE search tools -- search tools that specialize in medical and health care information.
