# Delete Documents by Reference

The DREDELETEREF index action instructs the DIH to delete one or more documents—specified by reference—from the child Content components. Use the following action syntax:

    http://DIHhost:IndexPort/DREDELETEREF?Docs=DocumentReferences&Field=FieldNames&DREDbName=DatabaseName

When you send this action to the DIH instead of to Content, note:

- `DIHhost` is the IP address (or name) of the machine on which the DIH is installed, and `IndexPort` is the number of the port that you use to send index actions to the DIH.
- This action deletes documents with the specified references that have the specified fields (if specified) and that are in the specified database (if specified) from all child Content components of the DIH.
