Hi, I am trying to find intersecting geo-hashes(upto precision length 6) of around 2lakhs polygons. I have tried using postgis st_geohash and st_intersect but it is very slow for my use-case. I need to index 2lakhs polygons and find their intersecting geohashes in 2 mins.
I read it that its possible to do so using lucene. http://opensourceconnections.com/blog/2014/04/11/indexing-polygons-in-lucene-with-accuracy/ Kindly, tell me how to do it or point me in the right direction. Regards, Swarn Avinash Kumar
