it's like Google f...ked up with their AI or something or lost their database with good links ...
Be anxious for nothing mate, this might have been an ordinary encounter you had that could have been resulted as a fault from your end, what i will ask you to do is to narrow your search well and thoroughly, remember google is loaded with lots of key words that may be related to your search but not necessarily be what you're looking for, that's why i commend you to narrow your search well and rephrase the key words used, and as for google loosing it reputation or trust and the likes as claimed by you just because of your personal experience, it would have been shutdown long time ago if matters like this were taken into consideration by billions of users across the globe, and i guess you check run your device if not already under attack.
