多场映射弹性搜索 [英] multi field mapping elasticsearch

问题描述

我试图在弹性搜索中映射一个多字段

I'm trying to map a multi field in elasticsearch

• 第一个字段 - 'in'应该包含所有索引列， / li>
  
• 第二个字段 - 'orig'应该包含正文。

例如：

    "findings": {
       "type": "multi_field",
       "fields": {
          "in": {
             "type": "string"
          },
          "orig": {
             "type": "string",
             "index":"not_analyzed"
          }
       }

一旦我创建这个和查询这是它的外观。

Once I create this and query this is how it looks.

当index ='否'是否意味着该字段永远不会被索引？

When index = 'no' does it mean the field will never be indexed at all?

  "findings": {
                  "type": "string",
                  "index": "no",
                  "fields": {
                     "in": {
                        "type": "string"
                     },
                     "orig": {
                        "type": "string",
                        "index": "not_analyzed"
                     }
                  }

推荐答案

index：no对不同类型有不同的含义。由于您的问题中发现字段是 String 根据 elasticsearch documentation 。

"index" : "no" has got different meaning for different types. Since findings field in your question is String it has following meaning according to elasticsearch documentation.

不表示它根本不可搜索（作为单个字段，它可能仍然包含在内）在所有）。设置为no禁用include_in_all。

no means that it won’t be searchable at all (as an individual field; it may still be included in _all). Setting to no disables include_in_all.

您不能直接搜索调查结果因为它有 index：no ，而您可以使用 findings.in 或发现.orig

you can not directly search for the field findings as it has got index: no while you can search it using findings.in or findings.orig
