在简要阅读了弹性搜索教程之后，我正在尝试使以下查询工作一段时间：

{
"query" :
{ 
    "size" : "10",
    "query" : {
        "bool" : {
            "must" : {
                "custom_score" : {
                    "query" : {
                        "text" : { "phrase" : {"query" : "iphone4", "type" : "phrase_prefix"}}
                    },
                    "params" : {
                            "param1" : 1000
                     },
                    "script" : "_score * param1 "
                }
            },
            "should" : [{ 
                "custom_score" : {
                    "query" : { "match_all" : {}},
                    "params" : {
                            "param2" : 0.001
                     },
                    "script" : "_score * doc['matches'].value * param2 "
                }
            },{
                "custom_score" : {
                    "query" : {"match_all" : {}},
                    "params" : {
                            "param3" : 0.001
                     },
                    "script" : "_score * doc['hits'].value * param3 "
                }
            }]

        }
    }
}
}

当我尝试运行它时，我收到以下错误：

}

你觉得我的错在哪里？关于我应该如何进行的任何建议？

您需要将嵌套查询与外部查询“合并”。试试这个：

{
    "query" : { 
        "bool" : {
            "must" : {
                "custom_score" : {
                    "query" : {
                        "text" : { "phrase" : {"query" : "iphone4", "type" : "phrase_prefix"}}
                    },
                    "params" : {
                            "param1" : 1000
                     },
                    "script" : "_score * param1 "
                }
            },
            "should" : [{ 
                "custom_score" : {
                    "query" : { "match_all" : {}},
                    "params" : {
                            "param2" : 0.001
                     },
                    "script" : "_score * doc['matches'].value * param2 "
                }
            },{
                "custom_score" : {
                    "query" : {"match_all" : {}},
                    "params" : {
                            "param3" : 0.001
                     },
                    "script" : "_score * doc['hits'].value * param3 "
                }
            }]

        }
    },
    "size" : "10"
}

如果您使用 curl 运行它，您可能还需要替换'为'\''
