如何按距离排序？

【解决方案1】：

我使用查询按距离对结果进行排序：

@professional_services =  
Professional::Service.search "*", where: {
  location: {
    near: {lat: @cordinate[0], lon: @cordinate[1]}, within: "10000km"
  }
}, 
order: [{
  _score: :desc}, {_geo_distance: {location: "#{@cordinate[0]},  
  #{@cordinate[1]}", order: "asc",unit: "km"}
}]

【解决方案2】：

如果你只想按距离排序可以使用下面的代码 sn -p

@professional_services =  
Professional::Service.search @keywords, order: {
    _geo_distance: {
        location: "#{@cordinate[0]}, #{@cordinate[1]}",
        order: "asc"
    }
}
