Hi,

https://doc.dovecot.org/2.4.2/core/man/doveadm-fts.1.html#fts-flatcurve-remo...

Thanks, seems like I overlooked it and thought it's gone because I got

doveadm fts flatcurve remove -A usage: doveadm [-Dv] [-f <formatter>] fts <command> [<args>] expand [-u <user>|-A] [-S <socket_path>] <search query> lookup [-u <user>|-A] [-S <socket_path>] <search query> optimize [-u <user>|-A] [-S <socket_path>] [<namespace>] rescan [-u <user>|-A] [-S <socket_path>] [<namespace>] tokenize [-u <user>|-A] [-S <socket_path>] <text>

which was only caused by not reenabling fts_flatcurve itself.

Best regards, Bjoern
