在 ElasticSearch 上按距离排序

Question

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？

这是一个语法错误，您应该使用 ] 而不是 } 关闭排序
