Search engines are software systems that index information on the web and allow users to search for that information. There are different types of search engines including crawler-based engines that use software to index web pages and human-powered directories that rely on human editors. Search engines work by using web crawlers to find new pages, algorithms to make sense of text and links, and search result pages (SERPs) to present results to users. Boolean operators like AND, OR, and NOT can be used to refine searches, and search engine optimization aims to affect a website's visibility in organic search results.
