1. 仅使用查询时分析器创建索引：

PUT /local_persons
{
  "settings": {
    "analysis": {
      "analyzer": {
        "person_search_analyzer": {
          "type": "custom",
          "char_filter": ["remove_special_chars"],
          "filter": ["lowercase"],
          "tokenizer": "whitespace"
        }
      },
      "char_filter": {
        "remove_special_chars": {
          "type": "pattern_replace",
          "pattern": "[^a-zA-Z0-9]",
          "replacement": ""
        }
      }
    }
  }
}

2. 使用特殊字符对数据进行索引：

PUT /local_persons/_doc/1
{
  "id": 1,
  "firstName": "Re'mo",
  "lastName": "D'souza",
  "email": "[email protected],
  "dateOfBirth": "1973-01-01",
  "isActive": 1
}

现在搜索查询时的人员：

方法 1：使用 query_string 搜索（查询时使用分析器）

GET /local_persons/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "query_string": {
            "query": "remo",
            "fields": ["firstName"],
            "analyzer": "person_search_analyzer"
          }
        },
        {
          "query_string": {
            "query": "dsouza",
            "fields": ["lastName"],
            "analyzer": "person_search_analyzer"
          }
        }
      ]
    }
  }
}

方法 2：使用匹配查询

GET /local_persons/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "firstName": {
              "query": "remo",
              "analyzer": "person_search_analyzer"
            }
          }
        },
        {
          "match": {
            "lastName": {
              "query": "dsouza",
              "analyzer": "person_search_analyzer"
            }
          }
        }
      ]
    }
  }
}

但上述两种方法均未得到预期的结果。
