ElasticSearch7.9.1, ik 分词无法插入数据

[xinyana]

elasticsearch7.9.1,ik 分词也是 7.9.1

前两步没有问题,但是插入数据报错 报错:Mapper 冲突

求解,非常感谢!

#1.创建 index
PUT /news

#2.设置分词
PUT /news/_mapping
{
  "properties": {
    "content": {
      "type": "text",
      "analyzer": "ik_max_word",
      "search_analyzer": "ik_max_word"
    }
  }
}

#3.插入数据
PUT gd/gd/1iNC
{
  "title": "这里是标题",
  "content": "这里是内容"
}

DELETE /news

第三步插入数据报错:

{
  "error" : {
    "root_cause" : [
      {
        "type" : "illegal_argument_exception",
        "reason" : "Mapper for [content] conflicts with existing mapping:\n[mapper [content] has different [analyzer]]"
      }
    ],
    "type" : "illegal_argument_exception",
    "reason" : "Mapper for [content] conflicts with existing mapping:\n[mapper [content] has different [analyzer]]"
  },
  "status" : 400
}
