Dreamio fails to map ElasticSearch Object type content

Hi,

For instance if I have this row in my index:

{ 
  "region": "US",
  "manager": { 
    "age":     30,
    "name": { 
      "first": "John",
      "last":  "Smith"
    }
  }
}

Dreamio correctly detect the “region” field and type and this field can be queried, and detects that there is a “manager” object, but does not map the content of the object, making it impossible to query its content such as the fields “manager.age” or “manager.age.name.first
