Search Engine
A search engine is a software system designed to search for information on the World Wide Web, typically returning results in the form of web pages, images, videos, or other online content. It works by crawling websites, indexing their content, and using algorithms to rank and retrieve relevant results based on user queries. Popular examples include Google, Bing, and DuckDuckGo.
Developers should learn about search engines to optimize websites for better visibility (SEO), integrate search functionality into applications, and understand how to work with search APIs for data retrieval. This is crucial for building content-heavy platforms, e-commerce sites, or any application where users need to find information efficiently, such as in enterprise search systems or recommendation engines.
