A search bar is a user interface element that allows individuals to input text to find information quickly. It is commonly found on websites and applications, enabling users to search for specific content, such as articles, products, or images. When a user types a query into the search bar, the system processes the input and displays relevant results. Search bars often include features like autocomplete suggestions, which help users by predicting their queries as they type. They are essential tools for enhancing navigation and improving user experience on platforms like Google, Amazon, and social media sites.
