"... we can find what we are looking for, whether those with the domains like it or not... "
Actually, those with the domains can prevent Google from indexing certain pages or even the entire site.
Search engines like Google use a technology called Robots. Search engine robots automatically scour the web returning information about each page they visit to the search engine's indexing search. This is then cache and correlated in a database.
Robots can be blocked by using a robots.txt file in the root directory of the web site. So, if your domain is foo.com, the corresponding robots.txt file would be at http://foo.com/robots.txt
