Elasticsearch - MissingMethodException在geo_point数组上运行distanceInKm [英] Elasticsearch - MissingMethodException on running distanceInKm on geo_point array

问题描述

我有一个具有geo_points数组的弹性搜索文档。我已经创建了映射：

  {
test：{
properties 
locations：{
type：geo_point
} 
} 
} 
} 
  

现在，我正在尝试创建一个查询，我想在其中对geo_points数组进行一些处理。我已经创建了我的查询：

  {
查询：{
 {
filter：{
script：{
script：sDistance = doc ['locations']。values [0] .distanceInKm（28.51818,77.096080） 
} 
} 
} 
} 
} 
  

我想计算点数（28.51818,77.096080）与位置数组中第一个元素的距离。

它给我这个错误： / p>

GroovyScriptExecutionException [MissingMethodException]（没有方法的签名：org.elasticsearch.common.geo.GeoPoint.distanceInKm（）适用于参数类型：（java.lang.Double，java .lang.Double）值：[28.51818，77.09608]]

我尝试使用 sDistance = doc ['locations'] [0] .distanceInKm （28.51818,77.096080）; ，但也导致相同的错误。

我在这里做错什么？

提前感谢

解决方案

您的脚本本身不应该检索第一个地理位置，但直接在位置字段之间调用 distanceInKm ，如下所示：

  { 
查询：{
过滤：{
过滤器：{
脚本：{
script：sDistance =位置] distanceInKm（28.51818,77.096080）; 
} 
} 
} 
} 
} 
  

在引擎盖下，第一个地理位置将被检索，距离将为计算出来。

I have an elasticsearch document which has an array of geo_points. I have created the mapping as:

{
    "test": {
        "properties": {
            "locations": {
                "type": "geo_point"
            }
        }
    }
}

Now, I am trying to create a query in which I want to do some processing on the array of geo_points. I have created my query like this:

{
    "query": {
        "filtered": {
            "filter": {
                "script": {
                    "script": "sDistance = doc['locations'].values[0].distanceInKm(28.51818,77.096080);"
                }
            }
        }
    }
}

I want to calculate the distance of the point (28.51818,77.096080) from the first element in the locations array.

It is giving me this error:

GroovyScriptExecutionException[MissingMethodException[No signature of method: org.elasticsearch.common.geo.GeoPoint.distanceInKm() is applicable for argument types: (java.lang.Double, java.lang.Double) values: [28.51818, 77.09608]]

I tried using sDistance = doc['locations'][0].distanceInKm(28.51818,77.096080); but it also resulted in the same error.

What am I doing wrong here?

Thanks in advance.

解决方案

Your script should not retrieve the first geo point by itself, but simply call distanceInKm on the locations field directly, like this:

{
  "query": {
    "filtered": {
      "filter": {
        "script": {
          "script": "sDistance = doc['locations'].distanceInKm(28.51818,77.096080);"
        }
      }
    }
  }
}

Under the hood, the first geo point will be retrieved and the distance will be computed on it.
