Re: Find the 100 closest neighbors to a point (lng, lat)
Anyone has an idea on which tool is the best to perform this task? This would be of a major help :-) Thanks for your answers!

Re: Find the 100 closest neighbors to a point (lng, lat)
Hi Adrien, thanks for your answer, but actually, I need something really optimized, so I guess ES is not the way to go. Can you think of better ways to actually do that? Thanks 2014-10-27 18:27 GMT+01:00 Adrien Grand adrien.gr...@elasticsearch.com: Hi Michael, You can do that using geo-distance sorting: http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-request-sort.html#_geo_distance_sorting It would probably not be optimal in the sense that elasticsearch will need to compute the distance for every matching document, but maybe it would still be fast enough?
