Fast Woo Order Lookup is a WordPress plugin designed to optimize the order and subscription search functionality in WooCommerce. By default, WooCommerce performs a general substring search that can be inefficient, especially for stores with a large number of orders. This plugin addresses the issue by creating a special-purpose index table using trigrams to significantly enhance search speed. After activation, it runs a background process to build this index, allowing for rapid searches by customer name, email, and other attributes.

While the plugin improves performance, it does require additional database space and initial time to generate the trigram table. It also addresses slow query performance related to meta_keys in the orders page, ensuring a more efficient experience for store owners. Fast Woo Order Lookup is a valuable tool for WooCommerce users looking to streamline their order management processes.
