How do you limit search results to one SERP per domain?

I thought I saw a post about it once

How do you limit search results to one SERP per domain? Another thing, my preferences are for 100 results per page. But when I send someone a link to the google results page, they only get 10. Is there something I can stick in the url to force 100 results?

I have the same question: how can I limit the results to 1 result per domain (not just in the top of the list but in the whole serps).

I also want to see the number of results returened. More precise: what I want to know is the number of *sites* that are relevant to te search.

I can't find this in Yahoo either.

Anyone?
