How It Affects Your App
The error ER_NO_FT_MATERIALIZED_SUBQUERY prevents the application from using materialized subqueries in full-text searches. This means that the application will not be able to use the full-text search feature to its fullest potential, as it will not be able to use materialized subqueries to optimize the search process. This can lead to slower search times and less accurate search results, which can have a negative impact on the user experience.
