Maybe you can even add these items into the cache upon delivery,
but someone more knowlegable than I would have to help you with that.
The drawback of getting thing in digest form -- you look like a boob
when answering late. I defer to Steffen's superior knowledge.
Don't blame yourself. It's not a problem to me receiving twice same answer.
I prefer more to less :) (not about unix tools)
But to answer your questions, I'm not really interested in purging the cache
data.
I just think that cache has expiration delay.
The only point is to get this "doveadm search" answering me in minutes instead
of hours.
Writing my original post, I didn't get if it was slow because of:
- data I'm searching are not cached at all? (headers like From, Date,
Message-ID...)
=> I wanted to know if dovecot allows to add some headers.
Stephen answered to that question.
- these data a cache, but for an extremely short time, like the user session
=> that's why I asked if it is possible to extend cache validity to at least
48h.
But for sure, if these data remain forever, it'll be better ! :)
- NFS limitations
=> do I have to re-install dovecot on my NFS servers? I prefer not.
