advSearch and getIds: how to include all resources except one?

I think I'm missing something here.. I want to include all resources, except one.

Both output nothing. Problem is I can't specify a parent, because the resources are located in the root. I also can't specify the entire list of resource id's, because the user can add more of them.

I also tried this (to include all children in the root folder?)



This also outputs nothing (zero for root is not an option I think ;-)

GetIds is installed and working with simple values, like:



So the question is, how to get all resources and then exclude a few. Thanks for any help!
