Enabling search indexing

To enable smart search indexing for all websites:

1. Open the Settings application.
2. Navigate to the System -> Search category.
3. Select the Enable smart search indexing check box.
4. Click Save.

The setting applies to both Azure Search indexes and locally stored indexes. You can now create search indexes, and the system automatically logs indexing tasks whenever content covered by an existing index is added, modified or deleted.

Processing of indexing tasks

By default, the smart search runs indexing tasks immediately when they are created.

For Azure Search indexing tasks, processing is ensured by the Execute Azure search tasks scheduled task. The task's scheduling interval is not important – the system automatically runs the task whenever a new Azure Search indexing task is logged (if another instance of the given scheduled task is not already running).

Scheduling indexing tasks for local indexes

For locally stored search indexes, you can disable automatic running of indexing tasks upon creation by adding the CMSProcessSearchTasksByScheduler key to the /configuration/appSettings section of your application's web.config file:

<add key="CMSProcessSearchTasksByScheduler" value="true" />

When you set this key to true:

• The system only logs the local search indexing tasks into the database without running them. You need to process the tasks periodically, for example using the Execute local search tasks scheduled task (runs every 4 hours by default).
• You cannot manually Rebuild indexes unless you also run the process that executes the indexing tasks.
