elasticsearch Elasticsearch:根映射定义具有不支持的参数

我正在创建一种通过Elasticsearch和Kibana搜索泰语单词的方法。我对映射有问题

PUT test
{
  "settings": {
    "analysis": {
      "analyzer": {
        "trigrams": {
          "tokenizer": "trigram_tokenizer",
          "filter": [
            "lowercase"
          ]
        }
      },
      "tokenizer": {
        "trigram_tokenizer": {
          "type": "ngram",
          "min_ngram": 3,
          "max_ngram": 3,
          "token_chars": []
        }
      }
    }
  },
  "mappings": {
    "true_name": {
      "properties": {
        "correct": { "type": "text", "analyzer": "trigrams" }
      }
    }
  }
}

像这样的错误

{
  "error" : {
    "root_cause" : [
      {
        "type" : "mapper_parsing_exception",
        "reason" : "Root mapping definition has unsupported parameters:  [true_name : {properties={correct={analyzer=trigrams, type=text}}}]"
      }
    ],
    "type" : "mapper_parsing_exception",
    "reason" : "Failed to parse mapping [_doc]: Root mapping definition has unsupported parameters:  [true_name : {properties={correct={analyzer=trigrams, type=text}}}]",
    "caused_by" : {
      "type" : "mapper_parsing_exception",
      "reason" : "Root mapping definition has unsupported parameters:  [true_name : {properties={correct={analyzer=trigrams, type=text}}}]"
    }
  },
  "status" : 400
}

不推荐使用映射类型。请参阅本文以了解有关删除映射类型的更多信息

在Elasticsearch 6.0.0或更高版本中创建的索引只能包含 单一映射类型。使用多个映射在5.x中创建的索引 类型将继续在Elasticsearch 6.x中像以前一样发挥作用。类型 将在Elasticsearch 7.0.0的API中被弃用，并且完全 在8.0.0中删除

如果您的JSON文档是这样的：

{
  "true_name": {
    "correct": "mapping types deprecated"
  }
}

然后，将创建索引映射-
