We'll have to get closer to the IMAP server, then. If you don't have TLS
enabled on your local dovecot you can probably log in and test with:

telnet localhost 143

Then:

a login <username> <password>
b select "INBOX"
c UID SEARCH SINCE 28-Jan-2022

To confirm that messages are found.

Then it's a matter of seeing that same conversation between Gnus and
Dovecot, to find where things are going wrong. You can set
`nnimap-record-commands' to t, then conduct a search, and also find
which of your " *nnimap localhost nil *nntpd**-373470" buffers
corresponds to this server. That should allow you to reconstruct the
conversation.

Another option would be to edebug the `gnus-search-imap-search-command'
function, and see what we're getting back from Dovecot.

Hopefully something in there will be revealing.
