dovecot - Dec 2019 - Dovecot 2.3.8 - How to force index creation for user/mailbox?

Thanks, but both commands didn't create dovecot.index. Only when I open
folder with IMAP client, the dovecot.index is created.

Wait, did you mean 'dovecot.index' file? That file is only created
occasionally, the actual index is kept in dovecot.index.log.

(~ 20000 emails, 30-50GB) - sometimes access to such mailbox takes very long
(~10 minutes), I would like to be able to create index for mailbox in
background, but I couldn't find any way to do it. So far I tried:

Neither of dovecot.index files are created (.cache, .log, .thread) - these
files are created when I open the folder with IMAP client. When mailbox is
not used for long time, the indexing takes very long time. So I'm looking
for any solution (preferably with doveadm) to manually reindex folders in
background.
