Metasearch engine

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.
