A meta-search engine is a search tool that sends user requests to several other search engines and/or databases and aggregates the results into a single list or displays them according to their source. Metasearch engines enable users to enter search criteria once and access several search engines simultaneously. Metasearch engines operate on the premise that the Web is too large for any one search engine to index it all and that more comprehensive search results can be obtained by combining the results from several search engines. This also may save the user from having to use multiple search engines separately.

The term "metasearch" is frequently used to classify a set of commercial search engines, see the list of search engines, but is also used to describe the paradigm of searching multiple data sources in real time. The National Information Standards Organization (NISO) uses the terms Federated Search and Metasearch interchangeably to describe this web search paradigm.

Q. academic and proffesional directories, commercial directories and portals,???
Asked by broadover - Wed Jan 17 22:53:15 2007 - - 1 Answers - 0 Comments

A. I haven't always found everything with Google Web Search. When I don't find something with Google and when I don't want to use a lot of different search engines, to save time, I may use a meta search engine. If I can't find the information with a meta search engine either, then I try to use a specialized search service.
