The above only shows messages in INBOX that have "SPAM" in subject. Did
you want it from all mailboxes? Then you should replace INBOX with *.
Otherwise the -Trash and -Junk lines are just ignored.

"to: jj at gioorgi.com" isn't a valid search query. Do you want something
like:

INBOX
  TO jj at gioorgi.com

or maybe

INBOX
  NOT SUBJECT SPAM
