=== Geo Bounds Aggregation

A metric aggregation that computes the bounding box containing all geo_point values for a field.


Example:

[source,js]
--------------------------------------------------
PUT /museums
{
    "mappings": {
        "doc": {
            "properties": {
                "location": {
                    "type": "geo_point"
                }
            }
        }
    }
}

{"location": "52.374081,4.912350", "name": "NEMO Science Museum"}

{"index":{"_id":6}}
{"location": "48.860000,2.327000", "name": "Musée d'Orsay"}

POST /museums/_search?size=0
{
    "query" : {
        "match" : { "name" : "musée" }
    },
    "aggs" : {
        "viewport" : {
            "geo_bounds" : {
                "field" : "location", <1>
                "wrap_longitude" : true <2>
            }
        }
    }
}
--------------------------------------------------
// CONSOLE

<1> The `geo_bounds` aggregation specifies the field to use to obtain the bounds
<2> `wrap_longitude` is an optional parameter which specifies whether the bounding box should be allowed to overlap the international date line. The default value is `true`

The above aggregation demonstrates how one would compute the bounding box of the location field for all documents with a business type of shop
