Geo Polygon Query

edit

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

edit
Option Description

_name

Optional name field to identify the filter

validation_method

Allowed Formats

edit
Lat Long as Array
edit

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
edit

Format in lat,lon.

GET /_search
{
    "query": {
        "bool" : {
            "must" : {
                "match_all" : {}
            },

                    }
                }
            }
        }
    }
}

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.
