Re-Index Changes To SharePoint Online List Folder Content

By default, your SharePoint Online source is set to recrawl a list folder if a change is detected in the folder when indexing. This can lead to long indexing times when frequent changes occur in list folders as your source can potentially re-index list folders continually.

To configure your source so that it doesn’t re-index changed list folders when indexing, you can set the RecrawlListFolderContentOnChange parameter in your source JSON configuration to false. In this case, your source indexes changes in list folders only during the next refresh/rescan/rebuild.

To set the RecrawlListFolderContentOnChange parameter value:

  1. In the Sources page, click your SharePoint Online source.

  2. In the Action bar, click More, and then Edit JSON.

  3. In the Edit a Source JSON Configuration panel, locate the RecrawlListFolderContentOnChange parameter, and set the value to either:

    • true (default) to re-index changed list folders when indexing.

    • false to not re-index changed list folders when indexing.

  4. Click Save to apply your change for subsequent indexing operations, or Save and rebuild source to apply your change and rebuild your source.
