Elicsearch has_child query / filter in Kibana 4

I cannot get the query (or filter) to has_child

function in Kibana 4. My code works in elasticsearch directly as a curl script, but not in Kibana 4, but I figured out that this is a key update feature. Can anyone shed some light?

The script trace as shown below runs in elasticsearch returning all parents that have a child:

    curl -XPOST localhost:port/indexname/_search?pretty -d '{
        "query" : {
            "has_child" : {
                "type" : "object",
                    "query" : {
                        "match_all" : {}
                    }
            }
        }
    }'

      

        
        
        
      

    

The above works fine. Then, to convert it to a JSON request to send to Kibana, I followed the general formatting rules: I dropped the curl line and added the index name (and sometimes an empty filter [], but it seems to make a big difference); no error is raised, but the entire dataset is returned.

    {
      "index" : "indexname",            
         "query" : {
            "has_child" : {
                "type" : "object",
                    "query" : {
                        "match_all" : {}
                    }
            }
        }
    }

      

        
        
        
      

    

Am I missing something? Has anyone else got a request has_child

to run in Kibana 4?

Thank you very much in advance
