Elasticsearch索引分析器设置

Question

我是弹性搜索的初学者。 我试图将分析器添加到索引中。 这是代码：

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

但是，这样做之后，我无法重新打开索引。 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"
            }
        }
    }
}
