Hi,

We are working on a POC using Bloomreach Developer Edition.

I have created a document type with a link field to refer another document type. When i am using the OOTB REST API to get the document field details on the link field, I am unable to expand and get the details. See below:

“gogreen:site”: [  
{  
“type”: “hippo:mirror”,  
“link”: {  
“type”: “local”,  
“id”: “73e73ccc-c98b-4000-aa21-64df135793db”,  
“url”: “[http://localhost:8080/site/api/documents/73e73ccc-c98b-4000-aa21-64df135793db](http://localhost:8080/site/api/documents/73e73ccc-c98b-4000-aa21-64df135793db)”  
}

I want to expand and get the details of this link using the OOTB API in the same response, instead of making another call - [http://localhost:8080/site/api/documents/73e73ccc-c98b-4000-aa21-64df135793db](http://localhost:8080/site/api/documents/73e73ccc-c98b-4000-aa21-64df135793db)

If we cannot expand, can we query the repository using some attributes, for instance - [http://localhost:8080/site/api/documents/73e73ccc-c98b-4000-aa21-64df135793db?siteName=xyz](http://localhost:8080/site/api/documents/73e73ccc-c98b-4000-aa21-64df135793db?siteName=xyz)
