I think you are describing DDG.
It's like they both just want to add something to the results, instead of saying "can't find anything else".
You usually don’t even need to remember them, for most somewhat popular sites you can just guess the bang, and it searches there.
And of course Google's own promoted results which are usually only vaguely related to the topic (for example if I search something programming-related, I'll get ads for Udemy or whatnot, but not even a specific course)
I should try the opposite though: when Google SERP is useless, try others.
I would gladly switch to a search engine that just got it all right in the way that Google pre-2010 did.
