mysql Server-Side Help
If you provide an argument to the help command, mysql uses it as a search string to access server-side help from the contents of the MariaDB Reference Manual. The proper operation of this command requires that the help tables in the MariaDB database be initialized with help topic information (see , "Server-Side Help").
If there is no match for the search string, the search fails:
