I remember the art of crafting the perfect google search query and knowing you'd eventually find that obscure bit of info. Now I have to quote nearly everything in my query and if a single result in the first 100 results is tangentially related, I'm grateful.
I've noticed this too, and I want to say it was only noticeable in the last year or two — but it seems to have gotten even worse over the last couple of weeks. Even when I quote something or -exclude a term it is still giving me what it thinks I actually wanted.
