It searches the World Wide Web in a systematic way for particular information specified in a textual web search query. The search results are generally presented in a line of results, often referred to as search engine results pages (SERPs). The information may be a mix of hyperlinks to web pages, images, videos, infographics, articles, and other types of files. As of January 2022, Google is by far the world's most used search engine, with a market share of 90.6%, and the world's other most used search engines were Bing, Yahoo!, Baidu, Yandex, and DuckDuckGo. | |-|-| | | wikipedia:: [Search engine](https://en.wikipedia.org/wiki/Search_engine) | ## [[Programming]] ## Tools - [[Google Search]] - [[DuckDuckGo]] - [[Bing]] - [[Perplexity]]
