Query all records by searching on all fields in a table

Is it possible to configure a search on a query all records action across all fields in a database table without needing to specify each field to search on?

It would work similar to the internal Xano search function we have when viewing database tables.

I note that we can select the entire db table when configuring search (as per screenshot attached), which then asks us to select an object (json) as the search criteria. Is there a working example of how the json needs to be structured for this to work?
