How do I search for "greetings of the day"

My users say that "greetings of the day" occurs in academic spam a lot. Since I don't trust my users, I opted to verify this bold claim.

But how do I search for a sequence of multiple words?

doveadm import -u restore@backup.invalid mdbox:/home/copymail/mdbox "" mailbox INBOX BODY "Greetings of the day" doveadm import -u restore@backup.invalid mdbox:/home/copymail/mdbox "" mailbox INBOX TEXT "Greetings of the day" (what's the difference betweeen BODY and TEXT?)

Is it even possible, given that "the" and "of" are probably stop words?
