[cekeriya (Zekeriya Kaplan)]

Hi everybody

I want my query to return only bucket[].size > 0
How can I do this?

                },
                {

                  "doc_count": 2
                }
              ]
            }
          },
          {
            "key": "+02129916178@53.205.223.157",
            "doc_count": 2,
            "NAME": {
