ElasticSearch geo distance filter with multiple locations in array - possible? -
let's have bunch of documents in elasticsearch index. each documents has multiple locations in array, this:
{ "name": "foobar", "locations": [ { "lat": 40.708519, "lon": -74.003212 }, { "lat": 39.752609, "lon": -104.998100 }, { "lat": 51.506321, "lon": -0.127140 } ] } according elasticsearch reference guide
the
geo_distancefilter can work multiple locations / points per document. once single location / point matches filter, document included in filter.
so, possible create geo distance filter checks locations in array?
this doesn't seem work, unfortunately:
{ "filter": { "geo_distance": { "distance": "100 km", "locations": "40, -105" } } } throws "queryparsingexception[[myindex] failed find geo_point field [locations]" since locations not single geo_point array of geo_points.
did specify geo_point mapping document?
