Even old Reddit has the "more from this subreddit" type links now so I imagine it breaks even if you scope your query to the old domain. I noticed most of this appeared after they launched the new Reddit UI, I don't remember having this problem in the past. Note that these are problems they could likely fix so I agree, but any platform can likely build a more context aware search as well.

Take a recent Reddit post and try on Google:
site:https://www.reddit.com/r/worldnews/comments/u3vzo2/russia_wa... arms
Even subreddit comment search on Google is flimsy due to Reddit not properly exposing the dates, so Google's indexed dates are usually wrong.
does work properly for those comments did index, e.g., https://breezethat.com/?q=%22Putin+is+in+no+shape%22+site%3A...
Aside from that, certainly, a site with its own indexing and awareness of its own internal structure can provide a better search experience than a third-party.
No, it absolutely does not. I have used Google to search Reddit for a string and got no results. That string was present in a Reddit comment open in another tab. It was a few years old so there is very little chance it hadn't been indexed yet.
This is a good move by Reddit (whose search has always been abominable). Many HN'ers have pointed out that they add "reddit" to their Google searches, ex: "<product X> reviews reddit". Why let Google get the ad dollars for that SERP?
Works for me every time. I haven't used Reddit search in 10 years.
I'm at a loss for why anyone would want to read Reddit comments in the first place though. At least on one of the top 100 subs.
I agree there are a lot of crap comments on the bigger default subs (as is the same with any forum) but those are relatively easy to ignore and recognize with experience. Or maybe I just have been using internet forums for too long !
