DOVEADM-FTS(1)                      Dovecot                     DOVEADM-FTS(1)
NAME
       doveadm-fts - Manipulate the Full Text Search (FTS) index
SYNOPSIS
       doveadm [GLOBAL OPTIONS] fts command [OPTIONS] [ARGUMENTS]
DESCRIPTION
       The doveadm fts COMMANDS can be used to manipulate the Full Text Search
       (FTS) index.
GLOBAL OPTIONS
       Global doveadm(1)
       -D
           Enables verbosity and debug messages.
       -O
           Do not read any config file, just use defaults.  The  dovecot_stor-
           age_version  setting  defaults  to  the  latest version, but can be
           overridden with
       -k
           Preserve entire environment for doveadm, not  just  import_environ-
           ment setting.
       -v
           Enables verbosity, including progress counter.
       -i instance-name
           If  using  multiple Dovecot instances, choose the config file based
           on this instance name.
           See instance_name setting for more information.
       -c config-file
           Read configuration from the given config-file. By default it  first
           reads  config  socket,  and  then  falls back to /etc/dovecot/dove-
           cot.conf. You can also point this to config socket of some instance
           running compatible version.
       -o setting=value
           Overrides  the configuration setting from /etc/dovecot/dovecot.conf
           and from the userdb with the given value. In order to override mul-
           tiple settings, the -o option may be specified multiple times.
       This  command  uses  by  default the output formatter flow (without the
       key=prefix).
OPTIONS
       -A
           If the -A option is present, the command will be performed for  all
           users.  Using  this  option  in  combination with system users from
           userdb { driver = passwd } is not recommended, because it  contains
           also  users  with  a  lower  UID  than  the one configured with the
           first_valid_uid setting.
           When  the  SQL  userdb  module  is  used,  make   sure   that   the
           userdb_sql_iterate_query setting setting matches your database lay-
           out.
           When using the LDAP userdb module, make sure that the userdb_fields
           setting  and userdb_ldap_iterate_fields setting settings match your
           LDAP schema. Otherwise doveadm(1) will be unable  to  iterate  over
           all users.
       -F file
           Execute  the command for all the users in the file. This is similar
           to the -A option, but instead of getting the list of users from the
           userdb,  they  are  read from the given file. The file contains one
           username per line.
       --no-userdb-lookup
           Do not perform userdb lookup. Use the USER environment variable  to
           specify the username.
       -S socket_path
           The  option's  argument  is either an absolute path to a local UNIX
           domain socket, or a hostname and port (hostname:port), in order  to
           connect a remote host via a TCP socket.
           This  allows  an  administrator to execute doveadm(1) mail commands
           through the given socket.
       -u user/mask
           Run the command only for the given user. It's also possible to  use
           '*' and '?' wildcards (e.g. -u *@example.org).
ARGUMENTS
       namespace
           The  name  of  a  namespace, e.g. the name of the shared namespace.
           When no namespace was given, the user's private namespace  will  be
           used.
COMMANDS
   fts optimize
       doveadm  [GLOBAL  OPTIONS] fts optimize [-u user | -A | -F file | --no-
       userdb-lookup] [-S socket_path] [namespace]
       Optimize the full text search index. This is also done automatically by
       the full text search engines, but this enforces it to happen.
   fts rescan
       doveadm  [GLOBAL  OPTIONS]  fts  rescan [-u user | -A | -F file | --no-
       userdb-lookup] [-S socket_path] [namespace]
       Scan what mails exist in the full text search index and  compare  those
       to  what actually exist in mailboxes. This removes mails from the index
       that have already been expunged and makes sure that  the  next  doveadm
       index  will  index  all the missing mails (if any). Note that currently
       most FTS drivers do not  implement  this  properly,  but  instead  they
       delete all the FTS indexes. This may change in the future versions.
   fts flatcurve check
       doveadm  [GLOBAL OPTIONS] fts flatcurve check [-u user | -A | -F file |
       --no-userdb-lookup] [-S socket_path] [mailbox ...]
       Run a simple check on Dovecot Xapian  databases,  and  attempt  to  fix
       basic  errors (it is the same checking done by the xapian-check command
       with the -F command-line option).
       mailbox is the list of mailboxes to process.  It  is  possible  to  use
       wildcards (* and ?) in this value.
       For  each mailbox that has FTS data, it outputs the following key/value
       fields:
       | Key | Value | | --- | ----- | | mailbox | The human-readable  mailbox
       name.  (key is hidden) | | guid | The GUID of the mailbox. | | errors |
       The number of errors reported by the Xapian library. | | shards  |  The
       number of index shards processed. |
   fts flatcurve remove
       doveadm [GLOBAL OPTIONS] fts flatcurve remove [-u user | -A | -F file |
       --no-userdb-lookup] [-S socket_path] [mailbox ...]
       Removes all FTS data for a mailbox.
       mailbox is the list of mailboxes to process.  It  is  possible  to  use
       wildcards (* and ?) in this value.
       For each mailbox removed, it outputs the following key/value fields:
       |  Key | Value | | --- | ----- | | mailbox | The human-readable mailbox
       name. (key is hidden) | | guid | The GUID of the mailbox. |
   fts flatcurve rotate
       doveadm [GLOBAL OPTIONS] fts flatcurve rotate [-u user | -A | -F file |
       --no-userdb-lookup] [-S socket_path] [mailbox ...]
       Triggers an index rotation for a mailbox.
       mailbox  is  the  list  of  mailboxes to process. It is possible to use
       wildcards (* and ?) in this value.
       For each mailbox rotated, it outputs the following key/value fields:
       | Key | Value | | --- | ----- | | mailbox | The human-readable  mailbox
       name. (key is hidden) | | guid | The GUID of the mailbox. |
   fts flatcurve stats
       doveadm  [GLOBAL OPTIONS] fts flatcurve stats [-u user | -A | -F file |
       --no-userdb-lookup] [-S socket_path] [mailbox ...]
       Returns FTS data for a mailbox.
       mailbox is the list of mailboxes to process.  It  is  possible  to  use
       wildcards (* and ?) in this value.
       For  each mailbox that has FTS data, it outputs the following key/value
       fields:
       | Key | Value | | --- | ----- | | mailbox | The human-readable  mailbox

       | The last UID indexed in the mailbox. | | messages  |  The  number  of
       messages  indexed  in  the  mailbox.  |  | shards | The number of index
       shards. | | version | The (Dovecot internal) version of the FTS data. |
