Hi @nvntkriz096
The Free plugin version uses a native WooCommerce search engine. It means that the search speed depends on many factors:
1. How many plugins do you have?
2. How many products do you have?
3. How your WordPress is optimized?
4. How your server is fast?
5. How big is the search scope?
Also, your product database may contain long product descriptions, which causes the database to be heavily loaded during searches. Please check how FiboSearch works when you disable the search in descriptions in WP Admin -> WooCommerce -> FiboSearch -> Search config (tab).
