Elasticsearch指数分析器设置

Question

我是一个初学者的弹性搜索。我试图添加一个分析器到我的索引。这里是编码：

PUT drug_mono6/_settings 
{ 
"analysis": { 
"analyzer": { 
    "attachment.content": { 
    "type": "custom", 
    "tokenizer": "Whitespace" 
    } 
} 
} 
} 

但是，我没有能够重新打开索引后，这样做。我收到的错误是：

{ 
"error": { 
"root_cause": [ 
{ 
"type": "exception", 
"reason": "Failed to verify index [drug_mono6/SMmaJ4iPTCSUHp-oedsadA]" 
} 
], 
"type": "exception", 
"reason": "Failed to verify index [drug_mono6/SMmaJ4iPTCSUHp-oedsadA]", 
"caused_by": { 
"type": "illegal_argument_exception", 
"reason": "analyzer [attachment] must specify either an analyzer type, or 
a tokenizer" 
} 
}, 
"status": 500 
}` 

有没有办法修改设置并删除更改？

Answer 1

这应该工作

PUT drug_mono6 
{ 
    "analysis": { 
     "analyzer": { 
      "attachment": { 
       "type": "custom", 
       "tokenizer": "whitespace" 
      } 
     } 
    } 
}
