elasticsearch - 无法在ElasticSearch中将映射更改为non_analyzed

Question

我有一个具有以下映射的文档类型:

GET my_index/my_doctype/_mapping
{
  "my_index": {
    "mappings": {
      "my_doctype": {
        "properties": {
          "@timestamp": {
            "type": "date",
            "format": "strict_date_optional_time||epoch_millis"
          },
          "@version": {
            "type": "string"
          },
          "prod_id": {
            "type": "string"
          },
          "host": {
            "type": "string"
          },
          "message": {
            "type": "string"
          },
          "path": {
            "type": "string"
          },
          "img_path": {
            "type": "string"
          },
          "tags": {
            "type": "string"
          }
        }
      }
    }
  }
}

我试图将某些字段从 analyzed更改为 non_analyzed，所以我运行了此请求:

PUT my_index/_mapping/my_doctype 
{
  "properties": {
    "prod_id": {
      "type": "string",
      "index": "not_analyzed"
    },
    "img_path": {
      "type": "string",
      "index": "not_analyzed"
    }
  }
}

但是我收到以下错误:

{
   "error": {
      "root_cause": [
         {
            "type": "illegal_argument_exception",
            "reason": "Mapper for [img_path] conflicts with existing mapping in other types:\n[mapper [img_path] has different [index] values, mapper [img_path] has different [doc_values] values, cannot change from disabled to enabled, mapper [img_path] has different [analyzer], mapper [img_path] is used by multiple types.

         }
      ],
      "type": "illegal_argument_exception",
      "reason": "Mapper for [img_path] conflicts with existing mapping in other types:\n[mapper [img_path] has different [index] values, mapper [img_path] has different [doc_values] values, cannot change from disabled to enabled, mapper [img_path] has different [analyzer], mapper [img_path] is used by multiple types.

   },
   "status": 400
}

如何将字段“prod_id”和“img_path”更改为 not_analyzed

Answer 1

您不能更改现有字段的映射。您有两种解决方案:

您可以删除索引，使用正确的映射重新创建索引，然后为数据重新索引

您可以创建not_analyzed子字段并为数据重新索引

第二种解决方案是这样的:

PUT my_index/_mapping/my_doctype 
{
  "properties": {
    "prod_id": {
      "type": "string",
      "fields": {
        "raw": {
          "type": "string",
          "index": "not_analyzed"
        }
      }
    },
    "img_path": {
      "type": "string",
      "fields": {
        "raw": {
          "type": "string",
          "index": "not_analyzed"
        }
      }
    }
  }
}

重新索引数据后，可以使用 prod_id.raw和 img_path.raw。
