elasticsearch - 在多字段 Elasticsearch 中设置值

Question

我用 flex 记录了以下结构:

    PUT /movies
{
  "mappings": {
    "title": {
      "properties": {
        "title": { 
          "type": "string",
          "fields": {
            "de": { 
              "type":     "string",
              "analyzer": "german"
            },
            "en": { 
              "type":     "string",
              "analyzer": "english"
            },
            "fr": { 
              "type":     "string",
              "analyzer": "french"
            },
            "es": { 
              "type":     "string",
              "analyzer": "spanish"
            }
          }
        }
      }
    }
  }
}

但是当我尝试记录这样的值时:

PUT movies/_doc/2
{
  "title": "fox",
  "field": "en"
}

我收到以下错误:

{
  "error": {
    "root_cause": [
      {
        "type": "illegal_argument_exception",
        "reason": "Rejecting mapping update to [movies] as the final mapping would have more than 1 type: [_doc, title]"
      }
    ],
    "type": "illegal_argument_exception",
    "reason": "Rejecting mapping update to [movies] as the final mapping would have more than 1 type: [_doc, title]"
  },
  "status": 400
}

也许我做错了，因为我刚接触 flex 。我的想法是创建一对一的映射，并且当我以任何一种语言搜索Fox时，由于它们都记录在数据库中，因此仅以英语返回结果。

您的映射表示映射类型为“标题”，但是在创建文档时，您使用PUT movies/_doc/2表示不存在的映射类型_doc，因此ES会尝试自动创建它，并且在较新版本的ES中，禁止使用多种映射类型。

您应该将其更改为:PUT movies/title/2
