v2.0 has "doveadm index" command to do this. There's no other good way to do this. > Does it worth? I mean...

Doing it via IMAP won't guarantee that everything the user's client needs is indexed/cached. Different clients need different things, Dovecot only indexes stuff that client requests. You'd have to look up from index files what the client wants indexed and then perform IMAP commands requesting those fields. Even the act of doing this may mess up caching decisions, because user may have changed client and now it's indexing unnecessary fields. (Actually now that I think of it, doveadm index has this same problem. Have to get that fixed.) With v2.0 you could if you use Dovecot proxy (or director) you can also proxy doveadm connections through it, so a "doveadm index" would always go to the correct server. http://wiki2.dovecot.org/Director at the bottom has some info how to set this up (works also with plain proxy, without director).
