Report on Meta Search Engines

A metasearch engine sends queries to multiple search engines and other data sources, then collates the results in some way and formats them for display. The data sources can be internal indexes, associated text search engines, database search engines, message archives, Intranet or webwide search engines, or even file servers. Meta search engines simply read each search results page and extract the text from the HTML (this is "screen scraping").

For systems which use a protocol to interact with multiple search engines, see the forthcoming SearchTools Report on Distributed Search.
