ElasticSearch geo_bounding_box coordinate format


I was following the ElasticSearch guide online to represent coordinates as "lat, lng" but it doesnt seem to be working until I flip everything around to "lng, lat". I even have to flip around top_left and bottom_right in order for the query to work.

Is anyone experiencing the same problem? Clearly this is not how the documentation says to use it, but it's only working when I format it this way.

Rails format

def self.search(params)
      tire.search( page: params[:page], per_page: 2 ) do
           query { all }
           filter :geo_bounding_box, location: { top_left: " -121.88596979687497, 37.33588487375733", bottom_right: " -122.43528620312497, 37.553946238118264" }
      end
end

CURL format

curl -X GET "http://localhost:9200/articles/article/_search?page=&per_page=2&size=2&pretty=true" -d '{"query":{"match_all":{}},"facets":{"condition":{"terms":{"field":"condition","size":10,"all_terms":false}}},"filter":{"geo_bounding_box":{"location":{"top_left":" -121.88596979687497, 37.33588487375733","bottom_right":" -122.43528620312497, 37.553946238118264"}}},"size":2}'

Solution

  • When geo point is specified as a string, it should be in "lat,lon" format. When it is specified as an array, it should be in [lon, lat] format.
