# IDXFieldPrefix

The field prefix to use for IDX field names.

When you index an IDX file, IDOL Server transforms it into XML by adding it to a sub-tree and assigning a prefix to each field. By default, the sub-tree uses the prefix that you specify in the `IDXFieldPrefix` configuration parameter (if you do not specify a value for the configuration parameter, it uses the default value, `DOCUMENT`).

To use another sub-tree name for an index action, add the `IDXFieldPrefix` index parameter.

Actions: | DREADD DREADDDATA
Type: | String
Default: | The value of the `IDXFieldPrefix` configuration parameter.
Example: | `IDXFieldPrefix=DOCUMENT`
