Elasticsearch中的嵌套查询

Question

我在获取与Elasticsearch一起使用的嵌套查询时遇到问题（如果我删除了查询字符串之一，则可以使用）。我要解决的问题是我有一个包含关闭列表的文档（关闭）。我想在条件满足另一个值的闭包列表中搜索一个值。那只是从argan
= 1的闭包中获得价值

{"query":{
  "bool":{
     "must":[
        {
           "nested":{
              "query":{
                 "query_string":{
                    "default_field": "closures.rating",
                    "query": "5"
                 },"query_string": {
                    "default_field": "closure.argang",
                    "query": "1"
                 } 
              },
              "path":"closures"
           }
       }
     ]
  }
}}

我正在得到这个错误响应；

     }

我的映射如下所示。

{
"closure": {
  "properties": {
     "name": {
        "type": "string"
     },
     "closures": {
        "type": "nested",
        "properties": {
           "argang": {
              "type": "string"
           },
           "rating": {
              "type": "string"
           }
        }
     },
     "coadr": {
        "type": "string"
     },
     "telnr": {
        "type": "string"
     }
  }
}
}

有人知道我在做什么错吗？

您的查询不是有效的查询。您需要使用适当的复合查询将其他查询组合在一起，而不能仅使用逗号并添加仅支持一个查询的另一个查询。

例如，您可以使用布尔查询并具有两个must子句，几乎是您的两个query_string。或者，也许您甚至可以切换到使用过滤器，并进行过滤查询。我将看一下本文中的示例：http :

documents/
。
