Google's corporate position, unless they recently changed it, is that they do not index porn sites. Other search engines choose to do so however...
They do, it's limited to mostly a few sites.
That's probably why the NSA is watching you...they get lonely and bored and Google isn't that gpod.
Consider this. The military found the internet to be insecure and not durable enough to support their needs in wartime, so they gave it to the US public.
Just saying.
