How They Work. Search engines use special computer programs called bots that crawl across the internet reading and cataloging web pages. When you type in a question, the search engine looks through its massive library and shows you the pages it thinks will answer you best.

Many Types Exist. There are web search engines like Google and Bing, metasearch engines that search other search engines, desktop search tools that find files on your computer, and vertical search engines that only search one topic like recipes or jobs.

Incredibly Fast. Even though the internet has billions of pages, a good search engine can find and rank the most useful ones in less than a second. This happens because search engines use super-powerful computers working together.

Always Learning. Modern search engines use artificial intelligence to understand what you really mean when you search, not just looking for exact words. They learn from what billions of people search for every day to get better results.
