Despite what I’ve read on a couple of SEO blogs recently, you can still find your supplemental results by using the following query:

site:your domain -view***

Well it works for me, anyhow. I mean it still returns woefully inaccurate results but at least it’s better than nothing.

I really don’t understand why Google won’t include supplemental results in Webmaster Tools but there you go. I would ask Matt Cutts but then he’d only disable this query too

UPDATE: The folks over at Quick Online Tips have come up with some new queries which are currently working to show supplemental results including

site:domain.com *-12345
