How Can You Search Only the Supplemental Index?

How can you see what pages of yours are supplemental?

I was using the www.domain.com/ *** to see what pages of mine were contained in the supplemental index, but it no longer seems to work.

Is there another way to see which pages are "supplemental" without doing a site: search and subtracting what you don't see? Thanks for any help.

Not that I know of, but a site:www.domain.com -inurl:www search is often interesting.

Yes, you did read that right: site:www.domain.com -inurl:www

site:www.domain.com -inurl:www
I do understand that on using this syntax, Google is suppose to display url's without "www"
Really surprised on seeing that it is showing supplemental results
Is that an error from their end?

Or try

site:www.domain.com -inurl:www.domain.com

The assumption is site: includes supps, but inurl: does not. Both assumptions are unreliable, but worth a try.
