Hi,

I'm using Dovecot 2.2.28 with fts. It seems to work fine almost things. But I found a bug (or my setting problem?)

My setting is "fts_autoindex=yes" in /etc/dovecot/conf.d/90-fts.conf Then, I have mailboxes like bellow:

a a/lot a/lot/of

There are some mails is in "a/lot" folder, then create sub like:

a/lot/of/apples

And move the mails from "a/lot" to "a/lot/of/apples" by MOVE command.

In this case, FTS function fts_backend_xx_update_expunge is called. But fts_backend_xx_update_set_build_key is not called.

Another case, follow functions are called and mails will be indexed.

fts_backend_xx_update_expunge() fts_backend_xx_update_set_build_key()

By the way, in the first case, I tried a command as bellow, then the mails ware indexed correctly:

# doveadm index -u user1@example.com \*

I think MOVE is better way to move mails than COPY+FLAG DEL+EXPUNGE. My settings problem? Any hints?
