Remember Google Code Search, and Google (Usenet) Groups? Back then, Google cared about this stuff. Now they seem only to want to show you furniture ads, or get you to use their Zoom knockoff, etc.
These days Google substitutes the heck out of searches. Perhaps it's better if you've logged in, but I'd rather hack my leg off with a rusty saw than voluntarily log in to an account just to search the web.
