弹性搜索中的嵌套布尔查询

Question

我试图在弹性搜索中进行查询,它将执行以下操作:我希望它检查具有(metropolitan_area为16 AND starts_at为05072013)或(metropolitan_id为16 AND starts_at"blank"的结果.

这是我当前的查询,但我觉得它需要以某种方式嵌套,我不确定如何做到这一点.

{
  "query" : { 
    "bool" : {
      "must" : [
        {
          "term" : {"user" : "a"}
        }, 
        { 
          "term" :{"metropolitan_area" : "16"}
        }
      ], 
      "must_not" : [], 
      "should" :   []
    }
  }, 
  "filter" : {
    "or" : {
      "filters" : [
        {
          "term" : {"user":"519"}
        }, 
        {
          "term" : {"user":"6"}
        }, 
        {
          "term" : {"user":"5"}
        }, 
        {
          "term" : {"user":"36"}
        }, 
        {
          "term" : {"starts_at":"05072013"}
        }, 
        {
          "term" : {"starts_at":"blank"}
        }
      ]
    }
  }
}

Answer 1

正确嵌套的布尔表达式如下所示:

{
  "filter": {
    "or" : [{
       "and" : [
          { "term" : { "metropolian_area" : 16 } },
          { "term" : { "starts_at" : 0123213 } }
       ]
    }, {
       "and" : [
          { "term" : ... },
          { "term" : ... }
       ]
    }]
  }
}

Answer 2

and,or和,not查询在elasticsearch 2.x中已弃用.Elasticsearch文档建议使用bool 查询.例如,您可以在过滤器上下文中编写嵌套的bool查询:

{
  "query":{
    "bool":{
      "must":[
        {
          "term":{
            "user":"a"
          }
        },
        {
          "term":{
            "metropolitan_area":"16"
          }
        }
      ],
      "filter":{
        "bool":{
          "should":[
            {
              "term":{
                "user":"519"
              }
            },
            {
              "term":{
                "user":"6"
              }
            },
            {
              "term":{
                "user":"5"
              }
            },
            {
              "term":{
                "user":"36"
              }
            },
            {
              "term":{
                "starts_at":"05072013"
              }
            },
            {
              "term":{
                "starts_at":"blank"
              }
            }
          ]
        }
      }
    }
  }
}
