A metasearch engine (or search aggregator) is an online information retrieval tool that uses the data of a web search engine to produce its own results.[1][2] Metasearch engines take input from a user and immediately query search engines[3] for results. Sufficient data is gathered, ranked, and presented to the users.
Problems such as spamming reduce the accuracy and precision of results.[4] The process of fusion aims to improve the engineering of a metasearch engine.[5]
Examples of metasearch engines include Skyscanner and Kayak.com, which aggregate search results of online travel agencies and provider websites, and Searx, a free and open-source search engine which aggregates results from internet search engines.
