I don't have the link, but I also remember reading this story. I tried googling but didn't have any luck either. I just wanted to let you know that you're not misremembering!
IMO the HN search isn't even worth using -- it's way too strict. Google's a lot better at finding relevance without the exact keywords.
And also, HN's title policy is unfortunate :( I wish we had the editorial freedom to give articles better, more meaningful titles... but the guidelines actively discourage that.
