What is range of Cloudant geospatial point's nearest neighbour search -

-

i using cloudant db geospatial index. cloudant has nearest neighbor search point. has parameter limit no of results. range of nearest neighbor. have requirement search in 500 mts. how can achieve same in cloudant.

you can specify range combining nearest neighbor parameter geometry parameter. example, following query find docs within 500 meters of specified lat/long:

https://account.cloudant.com/yourdatabasename /_design/yourdesigndocname/ _geo/yourgeoindexname ?lat=37.41511369 &lon=-122.2099019 &radius=500 &relation=contains &nearest=true

more information:

https://docs.cloudant.com/geo.html

update: sure add &relation=contains ensure results include locations within radius. have updated example above. if relation not included nearest neighbor return "all geojson documents in database order measured distance query point."

see documentation other relation types (i.e. contains, crosses, overlaps, etc.)
