elasticsearch - Elasticsearch OR查询

Question

谁能告诉我如何在elastisearch中编写以下Mysql查询

Select * from `table` WHERE `Name`='A' OR `Name`='B' order by `rank` DESC

我已经尝试了多种互联网解决方案

{

"sort":{"rank":{"order":"desc"}}, 

"query": {

    "query_string" : {
        "fields" : ["Name"],
        "query" : "A OR B"
    }


}

并且还尝试了以下代码

{

"sort":{"rank":{"order":"desc"}}, 

  "query" : {
    "bool": {
      "should": [
        {
          "match_phrase" : {
            "Name" : "A"
          }
        },
        {
          "match_phrase": {
            "Name": "B"
          }
        }
      ]

    } 
  }
}

您可以使用Bool-Filter和Order对所有文档执行此操作:

{
  "query": {
    "match_all": {}
  },
  "filter": {
    "bool": {
      "should": [
        {
          "term": {
            "Name": "A"
          }
        },{
          "term": {
            "Name": "B"
          }
        }
      ]
    }
  },"sort": [
    {
      "rank": {
        "order": "desc"
      }
    }
  ]
}

或具有范围查询的子集:

"query": {
    "range": {
      "JoinDate": {
        "lte": 1431051540
      }
    }
  }
