Metasearch engine

A metasearch engine (or <a href="/facts/Search_aggregator/LBNy0HfL">search aggregator</a>) is an online <a href="/facts/Information_retrieval/MFSmpeNw">information retrieval</a> tool that uses the data of a <a href="/facts/Web_search_engine/SRntsbz2">web search engine</a> to produce its own results. Metasearch engines take input from a user and immediately query search engines for results. Sufficient <a href="/facts/Data/AUBFN97o">data</a> is gathered, ranked, and presented to the users.
Problems such as <a href="/facts/Spamming/Qc9IL60W">spamming</a> reduce the <a href="/facts/Accuracy_and_precision/JQ47xXDq">accuracy and precision</a> of results. The process of fusion aims to improve the engineering of a metasearch engine.
Examples of metasearch engines include <a href="/facts/Skyscanner/Ds2WQl5x">Skyscanner</a> and <a href="/facts/Kayak.com/KdxBvQbX">Kayak.com</a>, which aggregate search results of online travel agencies and provider websites. <a href="/facts/SearXNG/dSe5l974">SearXNG</a> is a generic <a href="/facts/Free_software/IaoVtJXn">free</a> and <a href="/facts/Open-source/7X9rCdz4">open-source</a> search software which aggregates results from internet search engines and other sources like Wikipedia and is offered for free by more than 70 SearXNG providers.
