Search in all fields

Hi, is there a way to search in all database fields without choosing one category from the list?

I am using this code at the moment:
[pdb_list search=true search_fields=”zip,interests,city,country,last_name,first_name” default_search_field=”zip” suppress=false header_sort=true filter=”approved=yes”]

If I remove default_search_field=”zip” then he says please choose a category. And like this it only searches in the zip field.

Thank you!
