[Lucene.Net] [jira] [Created] (LUCENENET-462) Spatial Search skipping records

Spatial Search skipping records with small radius e.g. 1 mile
-------------------------------------------------------------
Key: LUCENENET-462
URL: https://issues.apache.org/jira/browse/LUCENENET-462
Project: Lucene.Net
Issue Type: Bug
Components: Lucene.Net Contrib
Affects Versions: Lucene.Net 2.9.4
Environment: .Net framework 4.0
Reporter: Mark Rodseth
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:
// Origin
private double _lat = 51.508129;

private const string LatField = "lat";
private const string LngField = "lng";
