One area where Google search is terribly broken is porn.
If your search for some specific term "$foo", nearly every result is just 'search site $bar for "$foo"', taking you to the site's search page, regardless of whether $foo is actually found on the site.
What does that have to do with porn?
how many people do you think search for $foo and the opposite?
On the other hand, when I use to search for anything near the city I lived in, porn showed up way too frequently
I swear the only reason people started using bing is because the search there actually worked well for porn.
