This might be the reason - makes sense. As I want to use dovecot to
access my email stored in maildir (for notmuch, as this is not modifying
thew mails when only used for searching), I think I can not use it this
way. Makes perfect sense.

I have only the local imap and gmane.

I think I will do the same here.

Sounds like the best solution - and then just bind notmuch-search to a
keyboard shortcut.

I tried the normal search on y imap folders, and it is incredibly slow
(folders with 10 000 and more emails). Also, my archive is split into
years, and a topic can span two years - so the normal imap search is not
an option for me here.

In contrast - quite helpful, as I understood why it is not working to
use notmuch for an imap backend. And as my setup is running nicely, I do
not intend to change it.

Thanks a lot,
