Right, I searched the Tay stories that way. I saw the second one but didn't link it because I was looking for stories from the aftermath, not the introduction. I missed the first one because the title didn't have Tay.
Most of the stories from your search don't fit either -- either referring to something else, or not having many HN comments (as I said I was looking for pre-edit).
The problem wasn't being unaware of the search feature.
