# Use DREADD to Index IDX and XML Files Directly

The `DREADD` index action (case sensitive) directly indexes an IDX or XML file that is located on the same machine as the IDOL Content component. For example:

    http://ContentHost:indexPort/DREADD?filename&optionalParams

where,

`ContentHost` | is the IP address or host name of the machine on which the IDOL Content component is installed.
`indexPort` | is the indexing port of the IDOL Content component (specified in the `IndexPort` parameter in the `[Server]` section of the IDOL Content component configuration file.
`filename` | is the file name or location of the IDX or XML file to index.
`optionalParams` | are any optional index action parameters that you want to add. NOTE: You must set the `DREDbName` parameter if your IDOL Content component configuration does not contain a field process to read the database from a field.

For a full list of available parameters for the `DREADD` action, refer to the IDOL Server Reference.
