Can't get text on a START_ARRAY at 14:21

ElasticSearch汇总请查看：ElasticSearch教程——汇总篇

在使用must，should以及must not的时候，有个需求是：某个字段可以是X，也可以是Y，甚至可以是Z（此处为描述可以是fangzhu,也可以是caoben），原本请求如下：

GET /ecommerce/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "name": "yagao"
          }
        }
      ],
      "should": [
        {
          "match": {
            "desc": ["fangzhu","caoben"]
          }
        }
      ],
      "must_not": [
        {
          "match": {
            "price": 25
          }
        }
      ],
     "minimum_should_match": 1
    }
  }
}

结果报错

{
  "error": {
    "root_cause": [
      {
        "type": "illegal_state_exception",
        "reason": "Can't get text on a START_ARRAY at 14:21"
      }
    ],
    "type": "illegal_state_exception",
    "reason": "Can't get text on a START_ARRAY at 14:21"
  },
  "status": 500
}

网上找了很久，未在国内的任何博客或者论坛上找到解决方案，幸运的是在国外的ElasticSearch社区中找到了解决方案，故以此作为记录，原链接为[Solved] Illegal State - START_ARRAY

修改后为

GET /ecommerce/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "name": "yagao"
          }
        }
      ],
      "should": [
        {
          "match": {
            "desc": "fangzhu"
          }
        },
        {
          "match": {
            "desc": "caoben"
          }
        }
      ],
      "must_not": [
        {
          "match": {
            "price": 25
          }
        }
      ],
     "minimum_should_match": 1
    }
  }
}

返回结果

  "timed_out": false,
  "_shards": {
    "total": 5,
    "successful": 5,
    "skipped": 0,

          "tags": [

          ]
        }

          "desc": "youxiao fangzhu"
        }
      }
    ]
  }
}
