      Returns:
      The coordinates in form of geoMapFeatures

      Parameters:
      solrFieldName - Name of the SOLR fields to parse
      results - Documents to parse
      Returns:
      A list of geo-coordinates as Location

    • getLocations

      public static List<IArea> getLocations(Object o)
      Parse geo-coordinates from the value of a SOLR field
