@Kdancy Rather than site search, I used Google. There's a method using Google by which you can find out how many pages of any site has been indexed by Google. For instance:

site:techstyles.com.au

So I appended a search term to that type of search. So:

site:classiccar.com 1937 terraplane serial number

Just to be clear, you place this text right there in the Google search box, not up in the address bar (unless of course you're using the Chrome browser, where the address bar IS ALSO the search box).
