I disagree with the "unique content" assessment. Every page on my site is unique, but only the "Google-important" ones appear in the /* search. I think most other sites also have unique pages, except for spam sites and blogs.
I have been useing this command.. the regular "site:" command does not mean anything but google has picked up your pages, must be stored away in supplimental index.. this command site:xxx/* are the pages that can be seen on searches... How do you get all your pages to show in this command is the question?
