Geo Polygon Query

Geo Polygon Query

edit

A query allowing to include 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

edit

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

edit

Lat Long as Array

edit

Format in [lon, lat], note, the order of lon/lat here in order to 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

edit

Format in lat,lon.

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

                }
            }
        }
    }
}

Geohash

edit

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

geo_point Type

edit

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

Ignore Unmapped

edit

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.
