There may be a bug, and I just yesterday noticed something weird in the rebuilding code. I'll have to look into that. But anyway, "search all" isn't the proper way to test this. Try instead with:

doveadm fetch guid all | sort | uniq | wc

When you removed indexes Dovecot no longer knew about copies of messages.
