elasticsearch - Elasticsearch 在创建索引时出错

Question

我是 ES 的新手...在网上找到了一个教程:

PUT /company
{
  "settings": {
    "index": {
      "number_of_shards": 1,
      "number_of_replicas": 1
    },
    "analysis": {
      "analyzer": {
        "analyzer-name": {
          "type": "custom",
          "tokenizer": "keyword",
          "filter": "lowercase"
        }
      }
    }
  },
  "mappings": {
    "properties": {
      "age": {
        "type": "integer"
      },
      "experienceInYears": {
        "type": "integer"
      },
      "name": {
        "type": "keyword",
        "analyzer": "analyzer-name"
      }
    }
  }
}

这有什么问题？我收到以下错误:

{
  "error": {
    "root_cause": [
      {
        "type": "mapper_parsing_exception",
        "reason": "Mapping definition for [name] has unsupported parameters:  [analyzer : analyzer-name]"
      }
    ],
    "type": "mapper_parsing_exception",
    "reason": "Failed to parse mapping [_doc]: Mapping definition for [name] has unsupported parameters:  [analyzer : analyzer-name]",
    "caused_by": {
      "type": "mapper_parsing_exception",
      "reason": "Mapping definition for [name] has unsupported parameters:  [analyzer : analyzer-name]"
    }
  },
  "status": 400
}

我知道是现场分析器导致了这个问题:)，但这不是正确的吗？

Answer 1

关键字 数据类型没有 分析仪 参数，正文 数据类型有。

检查文档中允许的两种数据类型的参数:

keyword

text

因此，您的名称属性映射应更改为此。

  ...
  "name": {
    "type": "text",
    "analyzer": "analyzer-name"
  }
  ...
