1st hit: Coffee Drinkers Have Slightly Lower Death Rates, Study Finds
2nd hit: Stieg Larsson's Death: Coffee Or Conspiracy?
The first one doesn't even have the phrase "death coffee" in the page! And in the second one it's split up with a colon in between (technically correct, but not a single phrase).
And only after that, come the expected results, where "death" is a modifier of "coffee" (coffee was so strong we called it "death coffee"), which is what you'd expect when you put a phrase in quotes, no?
Results I'm sure the old Google of a few years back would have presented me as first hits, too.
Ok Stieg Larsson is still the first hit, but as I said, it's technically correct. And now so are the rest of the results :D
BTW, to whoever made that Finderr.com page: It doesn't work quite correctly, if you search for `"death coffee"` it doubles the quotes. You probably need to re-think your query regex. Maybe you could modify it so that it includes the `allintext:` operator when you search for an exact phrase?
