Hi,  
How can I retrieve unique values in the array, i just want to get unique lat from the below collection.

```auto
"hits" {

        "function": {

            "geo_fence: [

                {

                    "lon": 131.35346094060401,

                    "lat": 41.178745565876852

                },

                {

                    "lon": 111.34948605187357,

                    "lat": 11.174765184567086

                },

                {

                    "lon": 161.34706945406595,

                    "lat": 31.173031962500268

                }

            ]

            },

            "function": {

                "geo_fence": [

                    {

                        "lon": 181.35346094060401,

                        "lat": 31.178745565876852

                    },

                    {

                        "lon": 111.34948605187357,

                        "lat": 11.174765184567086

                    },

                    {

                        "lon": 121.34706945406595,

                        "lat": 41.173031962500268

                    }

                ]

                }

    }

```

Can someone help me to achieve this ?

Thank you.

Do you want to get distinct values from an array in a single document? Elasticsearch has no specific method to analyze a single document, you may use terms aggregation with some filter to identify that single document.
