es 7.x 如何全局设置 custom analyzer ？？

[pkwenda]

PUT _all
{
  "settings": {
    "analysis": {
      "analyzer": {
        "my_analyzer": {
          "tokenizer": "ngram_one_word"
        }
      },
      "tokenizer": {
        "ngram_one_word": {
          "type": "ngram",
          "min_gram": 1,
          "max_gram": 16,
          "filter": [ "lowercase" ]
        }
      }
    }
  }
}

{
  "error": {
    "root_cause": [
      {
        "type": "invalid_index_name_exception",
        "reason": "Invalid index name [_all], must not start with '_', '-', or '+'",
        "index_uuid": "_na_",
        "index": "_all"
      }
    ],
    "type": "invalid_index_name_exception",
    "reason": "Invalid index name [_all], must not start with '_', '-', or '+'",
    "index_uuid": "_na_",
    "index": "_all"
  },
  "status": 400
}

不想一个一个设置，求解。

另外问一下能像以前那样 在 elasticsearch.yml 里面全局设置吗 ？
