您需要删除分析器名称中的空格：

    "analyzer": {
      " autocomplete": {       <--- remove initial space here
        "type": "custom",
        "filter": [
          "lowercase",
          "autocomplete_filter"
        ],
        "tokenizer": "standard"
      }
    ....
    "DESCRIPTION_AUTO": {
      "index_analyzer": "autocomplete",   <-- because there is no initial space here !!!
      "search_analyzer": "standard",
      "type": "string"
    }
