dovecot - Oct 2019 - 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 at backup.invalid mdbox:/home/copymail/mdbox
"" mailbox INBOX BODY "Greetings of the day"
doveadm import -u restore at 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?

If your looking for the entire strings "Greetings of the day"
anywhere,
then use

 	doveadm fetch ... TEXT "Greetings of the day"

else if any sequence of these words in the body, use

 	doveadm fetch ... BODY "Greetings" \
 		AND BODY "of" \
 		AND BODY "the"
 		AND DAY "day"
