Geo Distance Query
editGeo Distance Query
editFilters documents that include only hits that exists within a specific distance from a geo point. Assuming the following indexed json:
{ "pin" : { "location" : { "lat" : 40.12, "lon" : -71.34 } } }
Then the following simple query can be executed with a geo_distance
filter:
{ "bool" : { "must" : { "match_all" : {} }, "filter" : { "geo_distance" : { "distance" : "200km", "pin.location" : { "lat" : 40, "lon" : -70 } } } } }
Accepted Formats
editIn much the same way the geo_point
type can accept different
representation of the geo point, the filter can accept it as well:
Lat Lon As Properties
edit{ "bool" : { "must" : { "match_all" : {} }, "filter" : { "geo_distance" : { "distance" : "12km", "pin.location" : { "lat" : 40, "lon" : -70 } } } } }
Lat Lon As Array
editFormat in [lon, lat]
, note, the order of lon/lat here in order to
conform with GeoJSON.

Lat Lon As String
editFormat in lat,lon
.

Options
editThe following are options allowed on the filter:
|
The radius of the circle centred on the specified location. Points which
fall into this circle are considered to be matches. The |
|
How to compute the distance. Can either be |
|
Whether to use the optimization of first running a bounding box check
before the distance check. Defaults to |
|
Optional name field to identify the query |
|
Set to |
geo_point Type
editThe filter requires the geo_point
type to be set on the relevant
field.
Multi Location Per Document
editThe geo_distance
filter can work with multiple locations / points per
document. Once a single location / point matches the filter, the
document will be included in the filter.
