Geo Polygon Query

A query returning hits that only fall within a polygon of points. Here is an example:

GET /_search
{
    "query": {
        "bool" : {
            "must" : {
                "match_all" : {}
            },
            "filter" : {
                "geo_polygon" : {
                    "person.location" : {
                        "points" : [
                            {"lat" : 40, "lon" : -70},
                            {"lat" : 30, "lon" : -80},
                            {"lat" : 20, "lon" : -90}
                        ]
                    }
                }
            }
        }
    }
}

Query Options

Option Description

_name

Optional name field to identify the filter

validation_method

Set to IGNORE_MALFORMED to accept geo points with invalid latitude or longitude, COERCE to try and infer correct latitude or longitude, or STRICT (default is STRICT).

Allowed Formats

Lat Long as Array

Format as [lon, lat]

Note: the order of lon/lat here must conform with GeoJSON.

GET /_search
{
    "query": {
        "bool" : {
            "must" : {
                "match_all" : {}
            },
            "filter" : {
                "geo_polygon" : {
                    "person.location" : {
                        "points" : [
                            [-70, 40],
                            [-80, 30],
                            [-90, 20]
                        ]
                    }
                }
            }
        }
    }
}
Lat Lon as String

Format in lat,lon.

GET /_search
{
    "query": {
        "bool" : {
            "must" : {
                "match_all" : {}
            },
            "filter" : {
               "geo_polygon" : {
                    "person.location" : {
                        "points" : [
                            "40, -70",
                            "30, -80",
                            "20, -90"
                        ]
                    }
                }
            }
        }
    }
}
Geohash
GET /_search
{
    "query": {
        "bool" : {
            "must" : {
                "match_all" : {}
            },
            "filter" : {
               "geo_polygon" : {
                    "person.location" : {
                        "points" : [
                            "drn5x1g8cu2y",
                            "30, -80",
                            "20, -90"
                        ]
                    }
                }
            }
        }
    }
}

geo_point Type

The query requires the geo_point type to be set on the relevant field.

Ignore Unmapped

When set to true the ignore_unmapped option will ignore an unmapped field and will not match any documents for this query. This can be useful when querying multiple indexes which might have different mappings. When set to false (the default value) the query will throw an exception if the field is not mapped.
