Hello Warren English,
When creating a data source with Blob, you can select the Indexer schedule as shown on the screen. The Indexer will import Blob data into Azure AI Search at scheduled intervals based on the settings.
Once the Indexer is established, you can also directly modify the schedule settings through the Azure AI Search Portal.
Best regards,
Charlie
