There is verbatim and back in the day this is also what doublequotes meant.
Google has gotten away by blaming it on spam since back when matt_cutts was here, but I fail to see how spam can possibly be the reason why neither doublequotes nor verbatim works (edit:) unless spammers have found their way into Googles ranking algorithm to neuter all exact match operators.
They had it. The fact it doesn't work anymore is probably because some big brains at Google strongly believe that their AI knows better. Such hubris is the reason why Google sucks today and it absolutely rocked 20 years ago.
