Magento 2 Search Autocomplete improves SKU-based search by matching the typed SKU with product data in real time. As the user enters characters, the system checks the SKU field and displays instant suggestions. Magento 2 Search Autocomplete highlights exact or close matches, which helps shoppers find items faster, even if they know only part of the SKU. The feature can also show product images, names, and prices beside the SKU result. This reduces search errors, speeds up product discovery, and helps users locate specific items quickly.
