Question

(f.GeoDistance(g => g.Address.SuburbLocation, geoDistanceFilterDescriptor => geoDistanceFilterDescriptor
                                                                                                                            .Location(term.Location.Latitude, term.Location.Longitude)
                                                                                                                            .Distance(Settings.SurroundingSuburbDistanceRange)
                                                                                                                            .DistanceType(GeoDistance.Arc)));

如果郊区位置的值为0，如何用Address.Location（其他字段）替换SuburbLocation。

g.Address.SuburbLocation == 0吗？ g.Address.Location：g.Address.SuburbLocation
