[jira] [Closed] (SOLR-4767) Geofilt is not accurate

     [ https://issues.apache.org/jira/browse/SOLR-4767?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

David Smiley closed SOLR-4767.
------------------------------

    Resolution: Invalid

My my calculus, those points are ~90 kilometers apart, outside the query radius of 80.  For simple distance calculations try entering in the pair of points here: http://www.movable-type.co.uk/scripts/latlong.html (you can enter them in decimal degrees).
