For those not familiar with it, HN's search, provided by Algolia, has syntax for searching posts, comments, by author, within date ranges, and (for posts) above or below thresholds, and more.
I can call up specific tweets from years ago by searching keywords that I remember (or at least I used to be able to before Twitter nerfed search). Just sticks in the brain.
I have keyboard shortcuts to bring up the most common ones, but otherwise I just go find them in HN Search.
