A search engine is a software system that is designed to search for information on the World Wide Web. It accomplishes this by crawling the web using a web crawler, which is a program that follows links on the web to find new pages. The search engine then indexes the pages it finds and stores them in a database. When a user searches for something, the search engine uses its index to find the most relevant pages and returns them to the user.
