elasticsearch error: ScriptException[dynamic scripting for [groovy] disabled]

     es进行聚合查询时，需要对结果进行排序，默认是对聚合结果的数量排序的，难以满足需求，可以通过嵌套的聚合解决,部分代码如下：

{
            "track_scores":true,
            "from":0,
            "size":10,
            "min_score": 0.2,
            "query" : {
                "filtered":{
                    "query":{
                        "query_string":{
                            "query": "'.$keyword.'",
                            "fields":["name1","name2^3","name3^3"]
                        }
                    }
                }
            },
            "aggs":
            {
                "id1s":{
                    "terms":{
                        "field": "id1",
                        "size":15,
                        "order":{"max_score":"desc"}
                    },
                    "aggs":{
                        "max_score":{
                            "max":{
                                "script": "doc.rank"
                            }
                        }
                    }
                },
                "id2s":{
                    "terms":{
                        "field": "id2",
                        "size":10,
                        "order":{"max_score":"desc"}
                    },
                    "aggs":{
                        "max_score":{
                            "max":{
                            "script": "doc.rank"
                            }
                        }
                    }
                }
            },
            "sort": [
                { "rank": { "order": "desc" }},
                { "_score": { "order": "desc" }}
            ]
        }

     因使用了script,会出现   “nested: ScriptException[dynamic scripting for [groovy] disabled]; }]，[status] => 400，”，需要动态脚本支持：
在配置文件elasticsearch.yml文件末尾加上  “script.groovy.sandbox.enabled: true” 即可。
