Reading through previous comments ... yes smart to check for cached google results and use them only ... my experience about maybe 1 to 2 % of non cached results ever had any useful info in them, so ignoring non cached is the way to go - I say that as someone who typically conducted at least a couple hundred focused searches (ie the use of numerous switches which used to work with google) on google every day up until around 2014 or so - as well as a few other search engines to seek out the really hard to find stuff. [If it were easy it wouldn't have been something I'd be doing.]

Further comment though is, though I'm unsure if quotes in the search box do the same thing, what makes a really good search engine is if all the words placed in the search box, are included in results. I'm not seeing this ... in fact I just tested and a third of the page were results that only had one of the key words. I just modified the settings to turn off safe mode and set to all regions ... sadly the site now is just white apart from the search bar ... no results. Set it back and it's sort of working ...
