Scheduled index job

Describes the indexing scheduled job in an integration of Optimizely Search & Navigation with Optimizely Content Cloud (CMS).

The EPiServer.Find.Cms assembly ships with a scheduled job plug-in, which lets administrators reindex an entire site from the Optimizely Content Management System (CMS) admin mode. The job, Episerver Find Content Indexing Job, can be started manually or via the job scheduling feature.



You only need to schedule the indexing job for specific circumstances described below. CMS instantly indexes any content changes. If you run the indexing job when it is not necessary, you are unduly adding to the system load.

Use the scheduled job

There are two legitimate scenarios for using the scheduled indexing job to index all pages:

  • After installing the Optimizely Search & Navigation CMS integration for the first time. Otherwise, existing pages are only indexed when manually republished.
  • The automatic indexing failed, or pages should be reindexed for another reason.

When started manually, the job runs within the IIS server application pool and is interrupted by IIS when the Idle Time-out passes. By default, the timeout is set to 20 minutes. Indexing a large site may take more than 20 minutes, and it is not advisable to increase the timeout. Therefore, it is recommended to schedule the job, as the CMS scheduled job process is not affected by the timeout.

Log of indexing activity

At the completion of an indexing job, a report prints to the history log displaying execution time and number of pages indexed.

Indexing job: Reindexing completed.
ExecutionTime: 0minutes 18seconds
Number of pages indexed: 180

If an error occurs, the report notifies you where it occurred and gives the error message. Two types of errors are counted:

  • Page errors, relating to filtering or loading page.
  • Batch errors, relating to transmitting and indexing files to Optimizely Search & Navigation.


Indexing job: Reindexing completed.
ExecutionTime: 0minutes 16seconds
