Update both virtual indexes & FTS indexes

Will the following command:

doveadm index -A '*'

Ensure all Dovecot indexes are current (including virtual mailboxes) and also update FTS?  Other than the time/resources needed to parse all users/mailboxes - is there a reason not to schedule this to run on a regular (hourly?) basis?

My goal is to have my server constantly working...so my client isn't waiting for either virtual mailbox or Solr FTS updates.
