The concept of metasearch engine it is used in the field of computing to allude to system which is responsible for browse search engines to find data . Unlike conventional search engines, it does not have its own database, but it tracks in the databases of others.

The metasearch engines, therefore, seek the information in the archives and directories of search engines. The user, when performing a search, receives as a result a combination of what is found in the various external records.

The way to collect the data and to order what was found depends on each metasearch engine. In general, these tools have resources to organize the results according to the relevance of the websites detected.

The main benefit that metasearch engines offer is that they work with multiple search engines simultaneously. This increases the possibility of finding what is sought or obtaining a greater amount of results .

Among the negative aspects, the metasearch engine is slower than a conventional search engine because the databases of others are contacted systems . On the other hand, as each traditional search engine has its own methodology, the syntax used in the research may be inadequate in some cases.
