Christopher Currens updated LUCENENET-462:
------------------------------------------
Description:
Running a spatial query against a list of locations all within 1 mile of a
location returns correct results for 2 miles, but incorrect results for 1 mile.
For the one mile query, only 2 of the 8 rows are returned.
Locations & Test below:
{code}
// Origin
private double _lat = 51.508129;
private double _lng = -0.128005;
private const string LatField = "lat";
private const string LngField = "lng";
// Locations
AddPoint(writer, "Location 1", 51.5073802128877, -0.124669075012207);
AddPoint(writer, "Location 2", 51.5091, -0.1235);
