These engines search only a specific piece of the Internet. See the "Vertical Search Engines" on our Deep Web guide for more of these.
Why use a single search engine when you can use a Meta? All web search engines are based on algorithms --complex series of lexical orders -- when they are combined, they may actually compete/delete results from some searches. Combining results from two or more engines assures the researcher of a more complete list of informative websites.
