The response is an object with a header and a results array:

{
  "header": {
    "numFound": 119742,
    "maxScore": 1,
    "queryTime": 15,
    "page": 1,
    "pageSize": 10
  },

}

The results array contains Data Source objects. When aggregations are requested, an additional facets field is included in the response.
