I found a "*imap log*" buffer. When conducting the "since:1y" search,
the only log is:
--8<---------------cut here---------------start------------->8---
07:56:57 [FreeOffline] 10993 SELECT "General"
07:56:57 [FreeOffline] 10994 UID SEARCH SINCE 30-janv.-2022
--8<---------------cut here---------------end--------------->8---

there isn't any buffer with this name, only the *imap log*

Indeed: the nnimap-command used is:

--8<---------------cut here---------------start------------->8---
nnimap-send-command("UID SEARCH %s" "SINCE 30-janv.-2022")
--8<---------------cut here---------------end--------------->8---

which seems to be invalid:
+ because of the french localized version of the date (janv instead of jan)
+ because of the dot

--8<---------------cut here---------------start------------->8---
UID SEARCH SINCE 28-Janv-2022
UID SEARCH SINCE 28-Jan.-2022
--8<---------------cut here---------------end--------------->8---

both return:
--8<---------------cut here---------------start------------->8---
UID BAD Error in IMAP command SEARCH: Invalid search date parameter (0.001 + 0.000 secs).
--8<---------------cut here---------------end--------------->8---

in a direct session with dovecot.
