# PrintEngine

Set `PrintEngine` to `True` when you send the action through a DAH to return information for each result document to show the child server that the result comes from.

When you set `PrintEngine` to `True`, the response includes an `<autn:engines>` tag for each result, which includes the child server information in the format `X[.Y.Z...]`, where:

- the number of elements represents the number of levels in your DAH hierarchy
- each element corresponds to the ID of the child server that returned the response. The ID is the number of the child server in the parent configuration file.

For example, if you have a DAH, with a layer of sub-DAHs, and then a layer of child IDOL servers, a value of `3.2` for `<autn:engines>` represents a document coming from child server two of sub-DAH three of the top level DAH.
