尝试PUT edgeNGram tokenizer

Question

Amazon EWS上的弹性1.5。

所以我只想尝试使用以下分析器和标记器，但是会收到错误：

{
"settings": {
    "analysis": {
        "analyzer": {            
            "my_edge_ngram_analyzer": {
                "tokenizer": "my_edge_ngram_tokenizer",
                "filter": [
                    "lowercase"
                ]
            },
            "tokenizer": {
                "my_edge_ngram_tokenizer": {
                    "type": "edgeNGram"
                }
            }
        }
    }
}

错误：

{
  "error": "IndexCreationException[[pictures_testing] failed to create index]; 
  nested: ElasticsearchIllegalArgumentException[failed to find analyzer type [null] or tokenizer for [tokenizer]]; ",
  "status": 400

}

我尝试了各种排列，但还没有任何效果。我做错了什么？

您需要将令牌设备向上移动一级：

{
  "settings": {
    "analysis": {
      "analyzer": {
        "my_edge_ngram_analyzer": {
          "tokenizer": "my_edge_ngram_tokenizer",
          "filter": [
            "lowercase"
          ]
        }
      },
      "tokenizer": {
        "my_edge_ngram_tokenizer": {
          "type": "edgeNGram"
        }
      }
    }
  }
}
