在 ElasticSearch 上按距离排序

【中文标题】在 ElasticSearch 上按距离排序

【问题描述】：

我在弹性搜索中有这个查询来按他们的名字获取地点：

GET places/fastfood/_search

    "from" : 0, "size" : 10, 
    "query": 
        "bool": 
         "must": [
                 "regexp":  "name": ".*name.*" ,           
                 "term" :  "location_id" : id                           
        ]
            
    

name 和 id 被替换以匹配我的需要。 现在我想获取与名称和 ID 匹配但更接近所选位置的位置。假设我在提供的 location_id（城市，区域）中没有麦当劳，我应该得到最接近该位置的位置。

我在每个城市/区域都有一个名为 location 的字段，这是一个包含纬度、经度的字符串，定义为 geo_spot。然后也将纬度和经度定义为长。像这样：

"location": "33.785400,-84.38480",
"latitude": "33.785400",
"longitude": "-84.384800",

所以我尝试添加按位置排序，像这样，但我得到错误，有问题：

GET places/fastfood/_search

    "from" : 0, "size" : 10, 
    "query": 
        "bool": 
         "must": [
                 "regexp":  "name": ".*name.*" ,           
                 "term" :  "location_id" : location_id                           
        ]
            
    ,
    "sort": [
    
      "_geo_distance": 
        "location":  
          "lat":  26.112,
          "lon": -73.998
        ,
        "order":         "asc",
        "unit":          "km", 
        "distance_type": "plane" 
      
    

我做错了什么？我应该改变什么？

【参考方案1】：

这是一个语法错误，您应该使用 ] 而不是 关闭排序

【讨论】：

你能告诉我你是怎么知道的吗？

看看你的错误日志的结尾：JsonParseException[Unexpected close marker '': expected ']'
