Predictive search, also known as autocomplete or auto-suggest, is a feature that uses algorithms and user data to anticipate and suggest search queries as a user types into a search bar. This technology not only saves time by providing instant suggestions, but also helps users refine their search and find relevant results more efficiently. By analyzing previous search history, location, and other factors, predictive search offers personalized and accurate suggestions, making the search experience more intuitive and seamless. It is commonly used in search engines, e-commerce websites, and other online platforms to enhance user experience and improve search accuracy.
