Definition Edit

A metasearch engine (also spelled meta-search engine) is a search engine that scans several other search engines sequentially, eliminates duplicate search results, and then presents the combined search results to the user.

Overview Edit

The advantage of using a metasearch engine is that it covers a large number of search engines in a single search. The disadvantages of a metasearch engine include:

most don't search all of the largest engines, most don't give you more than 10 records from each search engine, and most list paid listings first.[1]
