Question

如果我执行以下操作，则会发生错误：

创建具有两个映射的索引
两个映射都具有相同的字段（在本例中称为thing）
thing个字段中只有一个"index": "not_analyzed"

以上呼叫可以完成上述操作：

DELETE /test/

PUT /test/
{
  "mappings": {
    "product": {
      "properties": {
        "thing": {
          "type": "string",
          "index": "not_analyzed"
        }
      }
    },
    "page": {
      "properties": {
        "thing": {
          "type": "string"
        }
      }
    }
  }
}

然后会出现以下错误：

# DELETE /test/
{ ... }

# PUT /test/
{
   "error": {
      "root_cause": [
         {
            "type": "mapper_parsing_exception",
            "reason": "Failed to parse mapping [page]: Mapper for [thing] conflicts with existing mapping in other types:\n[mapper [thing] has different [index] values, mapper [thing] has different [omit_norms] values, cannot change from disable to enabled, mapper [thing] has different [analyzer], mapper [thing] is used by multiple types.

         }
      ],
      "type": "mapper_parsing_exception",
      "reason": "Failed to parse mapping [page]: Mapper for [thing] conflicts with existing mapping in other types:\n[mapper [thing] has different [index] values, mapper [thing] has different [omit_norms] values, cannot change from disable to enabled, mapper [thing] has different [analyzer], mapper [thing] is used by multiple types.

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

Set update_all_types to true to update [search_quote_analyzer] across all types.]"
      }
   },
   "status": 400
}

有人可以解释为什么会这样吗？这是一个错误吗？

弹性＆＃34;类型＆＃34;机制是虚拟的。意思是，在较低级别（= lucene），索引的所有文档都是相同的＆＃34;类型＆＃34;。弹性＆＃34;类型＆＃34;除法仅通过添加＆＃34; _type＆＃34;字段并通过它过滤。这意味着您不能（在一个索引上）具有相同field_name和不同映射的2种类型 - 因为在较低级别它们是相同类型且它们处于冲突中！你定义了＆＃34; thing＆＃34;在＆＃34;产品＆＃34;输入not_analyzed，然后输入＆＃34; page＆＃34;你将其定义为＆＃34; string＆＃34;默认为＆＃34;分析＆＃34; - 这是一个不同的映射，发生冲突！要么使它们相同，要么改变其中一个字段名称。

Elasticsearch（2.3.2）＆＃34; not_analyzed＆＃34;在不同映射中具有相同名称的字段
