# UpdateN

The `UpdateN` parameter specifies index tasks to run when CFS is about to update fields in a document in IDOL Server. This is when a connector updates the metadata for a document but not the content. Tasks must be numbered starting from zero (0).

In the following example, `Update0` runs a Lua script when a document is about to be updated.

For information about the tasks you can run, and information about how to set them up, refer to the Connector Framework Server Administration Guide.
