1) each of those pages links to www.example.com
2) each of those pages (usually) has a PageRank of at least 4.
If you don't get a list of pages then it means that there are no links to www.example.com with a PR of at least 4.
Oh, and the fact that a page is in that list by definition means that it has been "noted by Google", i.e. Google is aware of it and uses it to calculate your ranking.
I think that's the main reason why it won't turn up in the link:www.example.com command at the moment.
As to hunting through the results, the alternative is to do a site search on this PR8 site for your domain name or link text - see whether Google can find it. Once again, it won't do for another month, unless freshbot helps out.
