为了解决您的问题，您可以使用阿拉伯语\u规范化标记过滤器，它将在索引之前从文本中删除音调符号。您需要定义一个自定义分析器，并且您的分析器应该如下所示：

"analyzer": {
    "rebuilt_arabic": {
      "tokenizer": "standard",
      "filter": [
        "lowercase",
        "decimal_digit",
        "arabic_stop",
        "arabic_normalization",
        "arabic_keywords",
        "arabic_stemmer"
      ]
    }
  }

analyzer api检查：

GET /_analyze
{
  "tokenizer" : "standard",
  "filter" : ["arabic_normalization"],
  "text" : "وَهَكَذَا في كُلّ عَقْدٍ"
}

分析仪结果：

{
  "tokens" : [
    {
      "token" : "وهكذا",
      "start_offset" : 0,
      "end_offset" : 9,
      "type" : "<ALPHANUM>",
      "position" : 0
    },
    {
      "token" : "في",
      "start_offset" : 10,
      "end_offset" : 12,
      "type" : "<ALPHANUM>",
      "position" : 1
    },
    {
      "token" : "كل",
      "start_offset" : 13,
      "end_offset" : 17,
      "type" : "<ALPHANUM>",
      "position" : 2
    },
    {
      "token" : "عقد",
      "start_offset" : 18,
      "end_offset" : 24,
      "type" : "<ALPHANUM>",
      "position" : 3
    }
  ]
}
