如何查询geo_distance_query和script_query组合？

我有一个索引，它有很多商店信息，还有位置和距离字段。给定一个geo_point，该索引基于查询顶部基于geo_distance_query这一点指向所有存储距离，并计算出距离应该小于当前存储距离字段值。

我认为script_query和geo_distance_query组合，不知道如何实现。

请尝试以下代码：

query: {
                bool: {
                    must: [
                        {
                            script: {
                                script: {
                                    inline: "doc['location'].arcDistance(" + _.lat + "," + _.lon + ") < doc['distance'].value"
                                    , lang: "painless"
                                }
                            }
                        }
                    ]
                }
            }

结果Elasticsearch错误：

[illegal_argument_exception] script_lang not supported [painless]

是否有人遇到并解决了这个问题，使用什么方法来实现查询？

更改代码：

{
bool: {
    must: [
        {
            script: {
                script: {
                    inline: "doc['location'].arcDistance(" + _.lat + "," + _.lon + ") < doc['distance'].value"
                    , lang: "groovy"
                }
            }
        }
    ]
}

}

也是错误：

message: '[script_exception] failed to run inline script [doc[\'location\'].arcDistance(31.89484,120.287825) < doc[\'distance\'].value] using lang [groovy]',

            "caused_by": {"type": "null_pointer_exception", "reason": null}
        }
    }]
}, "status": 500

}

Answer 1

您获得的错误，即null_pointer_exception，是因为business_stores_v1索引中的某个文档有一个空location字段，因此公式失败

doc['location'].arcDistance(...)

     null_pointer_exception here
