ElasticSearch 在字段中找不到分析器？

Question

我使用 PUT http://localhost:9200/test 创建这样的索引：

{
  "settings": {
    "number_of_shards": 1,
    "analysis": {
      "analyzer": {
        "sortable": {
          "type": "custom",
          "tokenizer": "keyword",
          "filter": [
            "lowercase"
          ]
        }
      }
    }
  },
  "mappings": {
  }
}

返回：

{"acknowledged":true}

然后确保分析器在那里： http://localhost:9200/test/_analyze?_analyzer=sortable&text=HeLLo

{"tokens":[{"token":"hello","start_offset":0,"end_offset":5,"type":"<ALPHANUM>","position":0}]}

所以我为它创建了映射： 作者：PUT http://localhost:9200/test/_mapping/company

{
  "properties": {
    "name": {
      "type": "string",
      "analyzer": "standard",
      "fields": {
        "raw": {
          "type": {
            "analyzer": "sortable"
          }
        }
      }
    }
}

这会返回：

{"error":{"root_cause":[{"type":"mapper_parsing_exception","reason":"no handler for type [{analyzer=sortable}] declared on field [raw]"}],"type":"mapper_parsing_exception","reason":"no handler for type [{analyzer=sortable}] declared on field [raw]"},"status":400}

怎么了？

您的company 映射需要修复为：

{
  "properties": {
    "name": {
      "type": "string",
      "analyzer": "standard",
      "fields": {
        "raw": {
          "type": "string",
          "analyzer": "sortable"
        }
      }
    }
}
