-+ SharePoint supports a granular authorization model that determines per-user access at the document level.

 These are the considerations when using this feature:
 
-+ If there is a requirement to implement a SharePoint content indexing solution with Cognitive Search in a production environment, consider create a custom connector using [Microsoft Graph Data Connect](/graph/data-connect-concept-overview) with [Blob indexer](search-howto-indexing-azure-blob-storage.md) and [Microsoft Graph API](/graph/use-the-api) for incremental indexing.
++ If there is a requirement to implement a SharePoint content indexing solution with Cognitive Search in a production environment, consider creating a custom connector with [SharePoint Webhooks](/sharepoint/dev/apis/webhooks/overview-sharepoint-webhooks) calling [Microsoft Graph API](/graph/use-the-api) to export the data to an Azure Blob container and use the [Azure Blob indexer](search-howto-indexing-azure-blob-storage.md) for incremental indexing.
 
 + There could be Microsoft 365 processes that update SharePoint file system-metadata (based on different configurations in SharePoint) and will cause the SharePoint indexer to trigger. Make sure that you test your setup and understand the document processing count prior to using any AI enrichment. Since this is a third-party connector to Azure (since SharePoint is located in Microsoft 365), SharePoint configuration is not checked by the indexer.
