BTW: looking for -site:news.ycombinator.com warren buffet- at Google does not work.
That's what I usually use. It's just one of those things that's passed on here, like oral tradition, rather than something written down in the guidelines of the official hacker news page.
Others are like, talking about what constitutes hacker news, and telling people not to complain about being downmodded.
(2) Still, either [site:news.ycombinator.com Warren Buffet] or [site:news.ycombinator.com Warren Buffett] returns 90-180 results for me from Google. Is there a specific recent result you're expecting that it's missing? If so, that's Google's limitation.
(3) There's also searchyc.com to try; it returns 157 results for [Warren Buffet] and 86 results for [Warren Buffett].
(2) Yes, it was about buying a company, the first search result in Google gave me a comment with a possible answer but its not the one that I was looking for, I linked to the top parent while in Hacker News but is not the one either. So it's not what I'm looking for.
(3) I can try to go to searchyc.com but still a waste of time.
This way you could stay on top of any Warren Buffett HN without having to search for it post hoc.
