Hi David, Thank you so much for the detailed reply. I've checked each and every lat lng coordinates and its a purely polygon. After some time I did one change in the lat lng indexing. Changed the indexing format.
Initially I indexed the latitude and longitude separated by comma Eg:- "location":["9.445890,76.540970"] Instead I indexed with space. "location":["9.445890 76.540970"] and it worked Also from your observation on IsWithIn predicate I tested with Intersects and I found there is a difference in the QTime. For IsWithin "QTime": 9 ResponseHeader": { "status": 0, "QTime": 9 }, When I used "Intersects" responseHeader": { "status": 0, "QTime": 26 } Thank you so much Regards dhanesh s.r
