你快到了，但创建索引时的有效负载结构应该是这样的：

PUT test
{
  "settings": {
    "analysis": {
       ...
    }
  },
  "mappings": {
    "properties": {
       ...
    }
  }
}

在你的情况下，这意味着：

PUT test
{
  "settings": {
    "analysis": {
      "filter": {},
      "analyzer": {
        "keyword_analyzer": {
          "filter": [
            "lowercase",
            "asciifolding",
            "trim"
          ],
          "char_filter": [],
          "type": "custom",
          "tokenizer": "keywords"
        },
        "edge_ngram_analyzer": {
          "filter": [
            "lowercase"
          ],
          "tokenizer": "edge_ngram_tokenizer"
        },
        "edge_ngram_search_analyzer": {
          "tokenizer": "lowercase"
        },
        "tokenizer": {
          "edge_ngram_tokenizer": {
            "type": "edge_ngram",
            "min_gram": 2,
            "max_gram": 5,
            "token_chars": [
              "letter"
            ]
          }
        }
      }
    }
  },
  "mappings": {
    "properties": {
      "name": {
        "type": "text",
        "fields": {
          "keywordstring": {
            "type": "text",
            "analyzer": "keyword_analyzer"
          },
          "edgengram": {
            "type": "text",
            "analyzer": "edge_ngram_analyzer",
            "search_analyzer": "edge_ngram_search_analyzer"
          },
          "completion": {
            "type": "completion"
          }
        },
        "analyzer": "standard"
      }
    }
  }
}
