Most search engines limit the number of results from a domain to make the list of search results more diverse and balanced. Even if Wikipedia has a lot of useful articles about "recursion", you'll only see the most relevant 2 results, followed by a link that invites you to check the full list of results from Wikipedia.
Google replaced the link with an expandable plusbox that lists 5 additional results from a site without having to open a new page.
