What do you set in the "column" field for adding a minimum words validation via the Field Validation module?

Question

I'm creating a validation rule on a text field via the Field Validation module. On the create screen it asks for "Column" and includes this description:

A column defined in the hook_field_schema() of this field.

I do not understand what I need to enter here. Can anyone explain?
