I am noticing with Google that if I do a site:www.domain.com - Google is now pulling in each of the sub-domains that I have active - I have a sitemap setup and registered in their Webmaster Console.
This appears to be something new. Is anyone else noticing this with their sites?
I'm not seeing groupings, but I am surprised to see other subdomains when I use the "www" in the site: operator - even the no-www urls get listed. Fortunately, using any other subdomain except "www" still seems to limit the results the way I expect.
