If the query engine cannot recognize that nothing in "filled torus" indicates anything remotely close to a desire for porn results, then it's just not good.
A DDG search for "full prison" with safe search off returns, in order: xvideos.com, pornhub.com, xnxx.com, xnxx.com, serco.com (holy shit something actually about prisons sort of), xxxparodyhd.net, pussyspace.com, fox.com/prison-break, youtube.com, youtube.com
That's ridiculously bad. I'm not sure it could be worse if they tried.
If there's one astoundingly obvious way that Google's results are superior, it's that apparently they first ask themselves "is the user looking for porn? [Yes/No]" and then proceed from there.
