doveadm index updates the indexes. doveadm fts rescan makes sure that after something has broken it makes sure to update all the mails to the index after indexing is done - so it by itself doesn't even add any missing mails to the index.(And with fts-lucene it's actually looking if there are any mails that were supposed to have been deleted already - with Solr it should do that too but the code isn't written yet. So I don't think that needs to be run nightly (if ever automatically).
