+Avoid the @code{UID SEARCH UID @var{message numbers} NOT SINCE

+(notably, some versions of Courier). Instead, use @code{UID SEARCH SINCE
+@var{date}} and prune the list of expirable articles within Gnus.
+
+When Gnus expires your mail (@pxref{Expiring Mail}), it starts with a
+list of expirable articles and asks the IMAP server questions like ``Of
+these articles, which ones are older than a week?'' While this seems
+like a perfectly reasonable question, some IMAP servers take a long time
+to answer it, since they seemingly go looking into every old article to
+see if it is one of the expirable ones. Curiously, the question ``Of
+@emph{all} articles, which ones are newer than a week?'' seems to be
+much faster to answer, so setting this variable causes Gnus to ask this
+question and figure out the answer to the real question itself.
+
+This problem can really sneak up on you: when you first configure Gnus,
+everything works fine, but once you accumulate a couple thousand
+messages, you start cursing Gnus for being so slow. On the other hand,
+if you get a lot of email within a week, setting this variable will
+cause a lot of network traffic between Gnus and the IMAP server.
