Magento's search_query table is a vital tool for user search functionality, offering extensive insight into user queries. However, its large size can affect search performance – raising a question: to truncate or not?

The solution lies in balanced optimization – removing unnecessary search terms without losing important data. Before doing so, backing up the table is crucial to prevent data loss. Consulting a Magento expert for this process is recommended. Regular maintenance of the search_query table is key for sustained search performance. An effective balance between data retention and performance optimization can greatly enhance Magento's search performance.
