Skill and persistence are sometimes required for a successful Google search, so an unsuccessful search should necessarily not be taken as evidence of absence of online discussion of the topic.
You can restrict your google search to one site (e.g., I got this thread on the first page by googling hermes site:lesswrong.com).
Recently in another topic I mentioned the "two bishops against two knights" chess endgame problem. I claimed it was investigated over two decades ago by a computer program and established that it is a win situation for the two bishops' side. Then I was unable to Google a solid reference for my claim.
I also remember a "Hermes Set Theory". It was something like ZFC, regarded as a valid Set Theory axiom system for 40 years, until a paradox was found inside. Now, I can't Google it out.
And then it was the so called "Baryon number conservation law", which was postulated for a short while in physics. Until it was found that a subatomic decay may in fact in/decrease the number of baryons in the process. I can't Google that one either.
Is that just me, or what?
