 | == 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. | 
 |  | 
 | The link:cmd-show-queue.html[show-queue] command provides online index status. | 
 |  | 
 | == ACCESS |

 |  | 
 | == SCRIPTING | 
 | This command is intended to be used in scripts. |
