Answer 1

从您的查询来看，您想要查看所有没有prices.info 值的文档。

只需将您拥有的must_not 部分移动到您拥有的bool 查询的第一级即可。请参阅以下内容以获得更清晰的信息：

原始查询：

{
  "query": {
    "bool": {
      "must": [
        { term }
        { term }
        { hasparent }
        { bool 
          - should 
             - must
             - must
             - must
             - must_not         <---- Remove this 
                - { exists }    <---- Copy this
        }
      ],
      "must_not": [],           <---- And add that here
      "should": [
        {}
      ]
    }
  }
}

伪代码解决方案：

{
  "query": {
    "bool": {
      "must": [
        { term }
        { term }
        { hasparent }
        { bool 
          - should 
             - must
             - must
             - must
        }
      ],
      "must_not": [
        { exists }     <--- Note this    
      ],
      "should": [
        {}
      ]
    }
  }
}

查询 DSL

以下是您要查找的查询：

   "query":{
      "bool":{
         "must":[
            {

               }

请注意，您不应该看到任何具有 prices.info 字段的文档。另请注意，我已简化查询以使其简单。

让我知道这是否有效！
