For now, I used LatLonPoint.newDistanceQuery(...) and
SloppyMath.haversinMeters to get the distance between center point and all
other points within 50m radius circle and sort them using Comparator.
I am able to get accurate results in < 10ms which is fine with me.
Code:
Query latlonQuery = LatLonPoint.newDistanceQuery("loc", minLat,
minLng,
50);
TopDocs docs = searcher.search(latlonQuery, 50);
Any other optimizations I can still do(Directory type etc) ?
Thanks,
