      If Elasticsearch is empty, this command will create the necessary indices
 | 
						|
      and then import data from the database into those indices.
 | 
						|
 | 
						|
      This command will also upgrade indices if the underlying schema has been
 | 
						|
      changed since the last run. Index upgrades erase index data.
 | 
						|
 | 
						|
      Even if creating or upgrading indices is not necessary, data from the
 | 
						|
      database will be imported into the indices, unless overridden with --no-import.
