I see tons of discussion on this and very few people mentioning the verbatim mode which completely fixes all of this toxic search behavior.
Among a tiny, informal survey of my nerdy/developer/tech friends literally none of them knew about this feature.
So based on the discussion happening now, and extrapolation, I am assuming most of HN also doesn't know.
After you do a search, choose `Tools -> All Results -> Verbatim`. This will give you the behavior that you used to get from google search.
