如何通過距離順序搜索搜索？

Question

@professional_services = 
  Professional::Service.search @keywords, where: {
    location: { 
      near: { lat: @cordinate[0], lon: @cordinate[1] }, 
      within: "100km"
    }
  }  

如何按距離排序此搜索？

Answer 1

如果您只想按距離排序，可以使用下面的代碼片段

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

Answer 2

我用查詢按距離對結果進行排序：

@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"}
}]
