I'm using a totally different set of things, but at least dovecot and 
clucene are agreeable.. ;-)

You should have a fts plugin to doveadm that should solve this issue:

doveadm fts rescan
doveadm fts optimize

That's what I use to trigger rebuilds.

# For using doveadm -A:
iterate_attrs = uid=user
iterate_filter = (objectClass=posixAccount)

Are you defining iterate_* for your userdb?
