=== Geo Polygon Query

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

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

==== Query Options

[cols="<,<",options="header",]
|=======================================================================
|Option |Description
|`_name` |Optional name field to identify the filter

|`ignore_malformed` |Set to `true` to accept geo points with invalid latitude or
longitude (default is `false`).
|=======================================================================

[float]
==== Allowed Formats

[float]
===== Lat Long as Array

Format in `[lon, lat]`, note, the order of lon/lat here in order to
conform with http://geojson.org/[GeoJSON].

[source,js]
--------------------------------------------------
{
    "bool" : {
        "must" : {
            "match_all" : {}
        },
        "filter" : {
            "geo_polygon" : {
                "person.location" : {
                    "points" : [
                        [-70, 40],
                        [-80, 30],
                        [-90, 20]

            }
        }
    }
}
--------------------------------------------------

[float]

Format in `lat,lon`.

[source,js]
--------------------------------------------------
{
    "bool" : {
        "must" : {
            "match_all" : {}
        },
        "filter" : {
            "geo_polygon" : {
                "person.location" : {
