弹性搜索地图对not_analyzed文档不敏感 [英] Elasticsearch Map case insensitive to not_analyzed documents

问题描述

我有一个带有以下映射的类型

I have a type with following mapping

PUT /testindex
{
    "mappings" : {
        "products" : {
            "properties" : {
                "category_name" : {
                    "type" : "string",
                    "index" : "not_analyzed" 
                }
            }
        }
    }

}

我想搜索一个确切的单词。这是为什么我设置为not_analyzed。
但问题是我想搜索小写或大写字母[不区分大小写]。

I wanted to search for an exact word.Thats why i set this as not_analyzed. But the problem is i want to search that with lower case or upper case[case insensitive].

我搜索它，并找到一种方式来设置案例

I searched for it and found a way to set case insensitive.

curl -XPOST localhost:9200/testindex -d '{
  "mappings" : {
    "products" : {
      "properties" : {        
        "category_name":{"type": "string", "index": "analyzed", "analyzer":"lowercase_keyword"}
      }
    }
  }
}'

是否任何方式做这两个映射到同一个字段？

Is there any way to do these two mappings to same field.?

谢谢..

推荐答案

我想这个例子满足你的需要：

I think this example meets your needs:

$ curl -XPUT localhost:9200/testindex/ -d '
{
  "settings":{
     "index":{
        "analysis":{
           "analyzer":{
              "analyzer_keyword":{
                 "tokenizer":"keyword",
                 "filter":"lowercase"
              }
           }
        }
     }
  },
  "mappings":{
     "test":{
        "properties":{
           "title":{
              "analyzer":"analyzer_keyword",
              "type":"string"
           }
        }
     }
  }
}'

从这里取得：如何在弹性搜索中设置记分器

它使用关键字标记器和字符串字段上的小写过滤器，我相信你会想要的。

it uses both the keyword tokenizer and the lowercase filter on a string field which I believe does what you want.
