I've noticed this many times too, particularly recently, and I call it "Google Alzheimer's" --- what was once a very powerful search engine that could give you thousands (yes, I've tried exhausting its result pages many times, and used to have much success finding the perfect site many dozens of pages deep in the results) of pages containing nothing but the exact words and phrase you search for has seemingly degraded…
Google by itself isn't very good, but Googling from the Google Chrome address bar these days is something else.
