Hi,
In a JSON request, you can add nested child documents as a single document or an array of documents. JSON data: { "id": "1", "single_child": { "id": "2" }, "children": [{ "id": "3" }, { "id": "4" }] } Response: { "responseHeader":{ "status":0, "QTime":1, "params":{ "q":"id:1", "fl":"id,single_child,children,[child]"}}, "response":{"numFound":1,"start":0,"numFoundExact":true,"docs":[ { "id":"1", "single_child": { "id":"2"}, "children":[ { "id":"3"}, { "id":"4"}]}] }} I'm trying to achieve the same with an XML request. What is the correct syntax for adding that single child as a labelled nested document in XML? Kind regards, Thomas
