This is a great way to find many great posts and learn from HN:

"things i learned" https://hn.algolia.com/?query=things%20i%20learned&sort=byPo...

"wish someone told" https://hn.algolia.com/?query=wish%20someone%20told&sort=byP...

"how did you" https://hn.algolia.com/?query=how%20did%20you&sort=byPopular...

I'm sure there are many others like this too!

works for comments too, although it’s pretty much hunting for long-tail keywords

“pm me”

“opportunity”

“pent up demand”

“I’d pay”

“I miss”

etc
