|  | == DESCRIPTION | 
|  | Gerrit supports online index schema upgrades. When starting Gerrit for the first | 
|  | time after an upgrade that requires an index schema upgrade, the online indexer | 
|  | will be started. If the schema upgrade is a success, the new index will be | 
|  | activated and if it fails, a statement in the logs will be printed with the | 
|  | number of successfully/failed indexed changes. | 
|  |  | 
|  | This command allows restarting the online indexer without having to restart | 
|  | Gerrit. This command will not start the indexer if it is already running or if | 
|  | the active index is the latest. | 
|  |  | 
|  | == ACCESS | 
|  | Caller must be a member of the privileged 'Administrators' group. | 
|  |  | 
|  | == SCRIPTING | 
|  | This command is intended to be used in scripts. |
