TAG UID SEARCH UNSEEN

(e.g. this on my INBOX)

----------------------------

. select inbox
* FLAGS (\Answered \Flagged \Draft \Deleted \Seen hasnoatt hasatt
* selected medeleted NonJunk receipt-handled)
* OK [PERMANENTFLAGS (\Answered \Flagged \Draft \Deleted \Seen hasnoatt
* hasatt selected medeleted NonJunk receipt-handled \*)]
* 887 EXISTS
* 1 RECENT
* OK [UNSEEN 882]
* OK [UIDVALIDITY 1148523981]
* OK [UIDNEXT 379340]
* OK [NOMODSEQ] Sorry, modsequences have not been enabled on this
* mailbox
* OK [URLMECH INTERNAL]
. OK [READ-WRITE] Completed
TAG UID SEARCH UNSEEN
* SEARCH 379334 379335 379336 379337 379338 379339
TAG OK Completed (6 msgs in 0.010 secs)
TAG SEARCH UNSEEN
* SEARCH 882 883 884 885 886 887
TAG OK Completed (6 msgs in 0.000 secs)

----------------------------

The second one being sequence numbers rather than UIDs.  It's the
"UID" in the command that makes the difference.
