A meta-search engine is a search engine that sends user requests to several other search engines and/or databases and returns the results from each one.

The ease of use and high probability of finding the desired page(s) make metasearch engines popular with those who are willing to weed through the lists of irrelevant 'matches'. Another use is to get at least some results when no result had been obtained with traditional search engines.
