Transferring smart folders

I have created smart folders on my old mac that I want to transfer to my new one. Just to be clear, I do not want to transfer the content, but only the "definition" or "programming".

For example, I have tried drag and drop contact smart folders using screen sharing but that does not work...

Any idea?

Maybe copying the smart foder file from the Libary might work, but I cannot find them...

thanks
