A search engine is a software system that helps people find information on the internet. It’s like a librarian that helps you find books in a library. Instead of searching through physical books, a search engine searches through web pages, images, videos, and other types of online content to find information related to your search query. A search engine, the service, can be accessed through a web browser, the infrastructure.

When you use a search engine, you type in a keyword or phrase related to the information you’re looking for. The search engine then uses a complex algorithm to search through its vast database of indexed web pages and other online content to find the most relevant results for your query. These results are typically displayed in a list format, with the most relevant results appearing at the top of the page.

Popular search engines include Google, Bing, Yahoo, and DuckDuckGo. Search engines have become an essential tool for finding information on the internet, and they have revolutionized the way people access and use information in the digital age.

Google is the default search engine of Safari.
