dovecot - Jul 2019 - Since multiple ,matches

I have a rule in sieve like the following:

if anyof (header :contains ["to"] [ "box",
"change", "cornell?, ?twitter?]) {
   setflag "\\Seen";
   fileinto :create "misc";
   stop;
}

The messages that come in are using address extensions, so user+twitter at
example.com, for example.

The trouble is, this sieve recipe doesn?t get triggered and the message gets
filed into the extension folder ?twitter? or ?cornell? instead of ?misc?.

I have a very similar recipe following that one:

if header :contains "to" "root" {
   setflag "\\Seen";
   addflag "$label5"; 
   fileinto :create "root";
   stop;
}

And that one works as I expect.

Is that multiple match format valid for :contains (I?ve only seen it used for
:regex)? I don?t get an error.

Is there a way to run a debug log for the sieve recipe? Preferably for a single
user.

Never mind, I figured out my (stupid) error.
