Question

How do I rescan or reindex email data with Dovecot Solr (Full Text Search)?

Answer

If this needs to be rebuilt for specific users, the root user can utilize the following command via SSH or the WHM Terminal to rescan mailboxes with Dovecot Solr (Full Text Search):

# /scripts/rescan_user_dovecot_fts --user=cpusername

Note: "cpusername" should be replaced by the cPanel username that owns the email account.

From the script's "help" output:

CONFIG_TEXT: Usage:
       rescan_user_dovecot_fts ( --user <username> | --help )
   This script will call a dovecot FTS (full text search) rescan for each
   mailbox on a specified account if the 'cpanel-dovecot-solr' RPM is
   installed. If not, the script informs that the RPM isn't installed and
   returns.

This command can be helpful if emails are not listed when searching the mailbox.

While the method above is on a per-user basis, this can be performed for the entire server by instead using the command below. This rebuilds the indexes completely for all users on the server:

# /usr/local/cpanel/3rdparty/scripts/cpanel_dovecot_solr_rebuild_index
