A search engine is a specialized computer program that retrieves and displays relevant results from a database based on a user-submitted search query. A popular example is Google, which provides suggestions of web pages based on keywords and other metrics when a user searches for information on the internet.
Widely used search engines include Google, Bing, Yahoo, Yandex, Ask.com, and DuckDuckGo. These websites employ highly complex algorithms to estimate the relevance and value of web pages as they relate to a given search query.
Search engines filter and locate information from a massive database using keywords and a multitude of other factors. They make it dramatically easier for users to find the relevant information they need on the internet.
Search engines serve to bridge the gap between search users and the vast amount of data available online. By selecting websites and presenting them in a ranked order of relevance and value, they help users efficiently find the correct answers to their queries.
