So people type URLs in the search box. Google changed the way it treats those queries last year: instead of showing information about a URL, it returns standard search results and the top result should be the page that corresponds to your query. This is a great way to avoid typosquatting sites, like flicker.com or twiter.com.
But what happens when Google doesn't find a page from a site included in the index? Until recently, it returned the standard "Your search did not match any documents." Now it returns more helpful information: results from websites with similar addresses, suggestions for queries and a way to identify the page by restricting the search to the domain/subdomain from my initial query.
