Failed to parse value [not_analyzed] as only [true] or [false] are allowed

通过如下代码手动建立mapping的时候报错

PUT /website
{
  "mappings": {
    "article": {
      "properties": {
        "author_id": {
          "type": "long"
        },
        "title": {
          "type": "text",
          "analyzer": "english"
        },
        "content": {
          "type": "text"
        },
        "post_date": {
          "type": "date"
        },
        "publisher_id": {
          "type": "text",
          "index": "not_analyzed"
        }
      }
    }
  }
}

错误如下

{
  "error": {
    "root_cause": [
      {
        "type": "mapper_parsing_exception",
        "reason": "Failed to parse mapping [article]: Could not convert [publisher_id.index] to boolean"
      }
    ],
    "type": "mapper_parsing_exception",
    "reason": "Failed to parse mapping [article]: Could not convert [publisher_id.index] to boolean",
    "caused_by": {
      "type": "illegal_argument_exception",
      "reason": "Could not convert [publisher_id.index] to boolean",
      "caused_by": {
        "type": "illegal_argument_exception",
        "reason": "Failed to parse value [not_analyzed] as only [true] or [false] are allowed."
      }
    }
  },
  "status": 400
}

百度了下，国内几乎没有任何相关文档或者博客有说如何解决，不过在stackoverflow.上倒是有解决方案，连接如下：

change elasticsearch mapping

官方文档上也有说明：Elasticsearch Reference [6.4] » Analysis » Analyzers » Keyword Analyzer

大致说的是现在index这个只能用true或者false了，如果想要不被分词就把数据类型设置为keyword

PUT /newwebsite
{
  "mappings": {
    "article": {
      "properties": {
        "author_id": {
          "type": "long"
        },
        "title": {
          "type": "text",
          "analyzer": "english"
        },
        "content": {
          "type": "text"
        },
        "post_date": {
          "type": "date"
        },
        "publisher_id": {
          "type": "keyword"
        }
      }
    }
  }
}

测试

GET /newwebsite/_analyze
{
  "field": "publisher_id",
  "text": "my-dogs" 
}

返回结果

{
  "tokens": [
    {
      "token": "my-dogs",
      "start_offset": 0,
      "end_offset": 7,
      "type": "word",
      "position": 0
    }
  ]
}
