为什么选择弹性搜索“not_analyzed”字段分为条件？ [英] Why Elasticsearch "not_analyzed" field is split into terms?

问题描述

  ... 
my_field：{
type：string，
index：not_analyzed
} 
 ... 
  

当我索引值为 my_field ='test-some-another'的文档时，该值被分为3个术语： test ， some ，另一个。

我做错了什么？

我创建了以下索引：

  curl -XPUT localhost：9200 / my_index -d'{
index：{
settings：{
number_of_shards 5，
number_of_replicas：2 
}，
mappings：{
my_type：{
_all：{
enabled ：false 
}，
_source：{
压缩：true 
}，
属性：{
my_field {
type：string，
index：not_analyzed 
} 
} 
} 
} 
} 
}'
  

然后我索引以下文档：

  curl -XPOST localhost：9200 / my_index / my_type -d'{
my_field：test-some-another
}'
  

然后我使用插件 https://github.com/jprante/elasticsearch-index-termlist与以下API：

curl -XGET localhost：9200 / my_index / _termlist

这给了我以下响应：

  {ok：true，_ shards：{总计：5，成功：5，失败：0}，条件：[test，some，another]} 
  p $ p> 
 
 
  
解决方案
通过运行实际上设置：
 
 
 
  curl localhost：9200 / my_index / _mapping？pretty = true  
 
 
 
该命令创建索引似乎不正确。它不应该包含index：{作为根元素。尝试这样：
  curl -XPUT localhost：9200 / my_index -d'{
settings：{
number_of_shards：5，
number_of_replicas：2 
}，
mappings：{
my_type：{
_all 
enabled：false 
}，
_source：{
压缩：true 
}，
属性：{
my_field：{
type：string，
index：not_analyzed
} 
} 
} 
} 
}'
  
 
I have the following field in my mapping definition:
...
"my_field": {
  "type": "string",
  "index":"not_analyzed"
}
...
When I index a document with value of my_field = 'test-some-another' that value is split into 3 terms: test, some, another.

What am I doing wrong?

I created the following index:
curl -XPUT localhost:9200/my_index -d '{
   "index": {
    "settings": {
      "number_of_shards": 5,
      "number_of_replicas": 2
    },
    "mappings": {
      "my_type": {
        "_all": {
          "enabled": false
        },
        "_source": {
          "compressed": true
        },
        "properties": {
          "my_field": {
            "type": "string",
            "index": "not_analyzed"
          }
        }
      }
    }
  }
}'
Then I index the following document:
curl -XPOST localhost:9200/my_index/my_type -d '{
  "my_field": "test-some-another"
}'
Then I use the plugin https://github.com/jprante/elasticsearch-index-termlist with the following API:

    curl -XGET localhost:9200/my_index/_termlist

That gives me the following response:
{"ok":true,"_shards":{"total":5,"successful":5,"failed":0},"terms": ["test","some","another"]}
解决方案
Verify that mapping is actually getting set by running: 

curl localhost:9200/my_index/_mapping?pretty=true 

The command that creates the index seems to be incorrect. It shouldn't contain "index" : { as a root element. Try this:
curl -XPUT localhost:9200/my_index -d '{
  "settings": {
    "number_of_shards": 5,
    "number_of_replicas": 2
  },
  "mappings": {
    "my_type": {
      "_all": {
        "enabled": false
      },
      "_source": {
        "compressed": true
      },
      "properties": {
        "my_field": {
          "type": "string",
          "index": "not_analyzed"
        }
      }
    }
  }
}'
