The following two scheduled tasks are related to the Smart search module:
| • | Optimize search indexes - performs index optimization (defragmentation resulting in better performance, particularly in the case of large indexes). By default executed once per week. |
| • | Execute search tasks - executes indexing tasks (created and executed automatically when the indexed content changes) that were not completed successfully on their automatic execution. By default performed every 4 hours. |

Please refer to the Development -> Scheduler chapter for more information about scheduled tasks.
