Because of the change to BKD trees for `geo_point` type, in order to **efficiently** find the closest point in a stored database to a given point a simple search with limit on size is enough?

```auto
GET geodatabase/location/_search
{
	sort: {
		_geo_distance: {
			coordinates: {
				lat: 23,
				lon: 23
			},
			order: "asc",
			unit: "km"
		}
	},
	size: 1
}

```

Previously we would also filter by `geohash_cell` with a precision of 5 and decrease it until a match was found.
