因此，我一直在尝试添加带有参数的唯一令牌过滤器，而不在我的自定义分析器中创建单独的令牌过滤器。
根据文档，一个带有参数的令牌过滤器的示例不需要创建单独的令牌过滤器：https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-length-tokenfilter.html#analysis-长度tokenfilter analyze ex

    {
      "analyzer": 
      {
        "deba_analyzer": 
        {
          "char_filter": ["html_strip"],
          "tokenizer": "uax_url_email",
          "filter": ["lowercase","stop","kstem",{"type": "unique","only_on_same_position": true}]
        }
      }
    }
  },

    {
      "name": 
      {
        "type":"text"
      }
    }
  }
}

然而，直截了当地说，这给了我一个错误：

"reason" : "Failed to load settings from [{\"analysis\":{\"analyzer\":{\"deba_analyzer\":{\"filter\":[{\"only_on_same_position\":true,\"type\":\"unique\"}],\"char_filter\":[\"html_strip\"],\"tokenizer\":\"uax_url_email\"}}}}]",
"caused_by" : {
  "type" : "illegal_state_exception",
  "reason" : "only value lists are allowed in serialized settings"
}
