# IndexUID

Add an identification string to a document tracking event. If the index action normally generates a document tracking event, Distributed Index Handler adds this identification string to the event. You can then use this string to query the event server and track the progress of the index action.

Set `IndexUID` to a string identifier that you want to use to identify related document tracking events.

NOTE: Not all index actions generate document tracking events. If the index action does not normally generate a document tracking event, this parameter has no effect.

Type: | String
Default: |
Example: | `IndexUID=12345abcd`
