This has become so frustrating as of late, especially when you search for something like "c++ map" and it decides to completely ignore the "c++" part of your search, leaving you with pages of actual maps. Slightly exaggerated example since I can't remember any concrete ones off the top of my head, but the actual situation happens way too often.
I think this is a function of trying to make searches more effective for unsophisticated users at the expense of users who know how to be more precise.
Similar to Apple and GNOME, it ends up penalizing the expert users to cater to non-expert users.
This is why you need to have the regular interface for people who shouldn't be expected to be experts, but have a separate interface for people who know what they are doing, because supporting both types of users is often mutually exclusive.
It doesn't happen to me so it doesn't exist does not apply in this case
Google search doesn't really work for power users anymore and I don't see that changing for the better anytime soon.
