Who do I communicate a big cs-cart bug to?

CS-Cart 4.17.1

Go to backoffice panel, with the global search at the top right, type v and go to: Sorry, service is temporarily unavailable.

You can check page source code to see error details at the bottom

this is the result of source code:
Tygh\Exceptions\AException

The error shows that the table _search is full. I’m not familiar with that table. Are you using a third party addon for search? Maybe the table needs to be optimized.?

This is default temporary table which is created during search process

I suggest to adjust the configuration parameters for temporary tables in MySQL.

Thank you;
given your great experience, is there a way to limit the CS-cart API to product tables only so that whoever has the key cannot access the tables relating to customers/orders?
