使用netstat -lntp来看看有侦听在网络某端口的进程。当然,也可以使用 lsof。

多层nested的多条件查询

Elasticsearch | 作者 meowCoder123 | 发布于2022年05月17日 | 阅读数:1705

现在数据结构中嵌套了两层nested 结构如下
{

    "mappings":{
        "properties":{
           
            "lisCheckJson":{
                "type":"nested",
                "properties":{
                    "lisCheckItemList":{
                        "type":"nested",
                        "properties":{
                            "itemName":{
                                "type":"keyword"
                            },
                            "resultChar":{
                                "type":"keyword"
                            }
                        }
                    }
                }
            }
        }
    }
}
数据内容如下

{
                "lisCheckJson": [
                    {
                        "lisCheckItemList": [
                            {
                                "resultChar": "8.3",
                                "itemName": "1"
                            },
                            {
                                "resultChar": "3.93",
                                "itemName": "2"
                            },
                            {
                                "resultChar": "144",
                                "itemName": "3"
                            }
                        ],
                        "lisCheckItemList": [
                            {
                                "resultChar": "8.3",
                                "itemName": "1"
                            },
                            {
                                "resultChar": "3.93",
                                "itemName": "2"
                            },
                            {
                                "resultChar": "144",
                                "itemName": "3"
                            }
                        ]
                      
                    }
                ]
            }
 
预期结果:
我想查询出在同一个lisCheckItemList下的 resultChar=8.3 同时itemName=2 同时resultChar=144 同时 itemName=3 的数据 但我现在的查询是只要在同一个lisCheckJson中,不在同一个lisCheckItemList下的数据满足条件的也会查出来,请问该如何解决
