Question

这是我的设置文件 -

{
    "settings": {
        "mappings": {
            "default": {
                "properties": {
                    "AIRPORT_CODE": {
                        "type": "text"
                    },
                    "PROVINCE_NAME": {
                        "type": "text"
                    },
                    "AIRPORT_NAME": {
                        "type": "text"
                    },
                    "CITY_NAME": {
                        "type": "text"
                    },
                    "TYPE": {
                        "type": "keyword"
                    },
                    "COUNTRY_NAME": {
                        "type": "text"
                    }
                }
            }
        }
    }
}

以下是我摄入索引的2个文件 -

文档 - 1

{
  "AIRPORT_CODE": "SQA",
  "PROVINCE_NAME": "California",
  "AIRPORT_NAME": "Santa Ynez Airport",
  "CITY_NAME": "SANTA YNEZ",
  "TYPE": "AIRPORT"
}

文件 - 2

{
  "PROVINCE_NAME": "SANTIAGO",
  "CITY_NAME": "SANTIAGO",
  "COUNTRY_NAME": "DOMINICAN REPUBLIC",
  "TYPE": "HOTEL"
}

这是我的搜索查询 -

{
    "size": 4,
    "timeout": "2m",
    "query": {
        "bool": {
            "must": [
                {
                    "multi_match": {
                        "query": "SQA"
                    }
                }
            ],
            "filter": [
                {
                    "term": {
                        "TYPE": "AIRPORT"
                    }
                }
            ]
        }
    },
    "explain": false
}

“TYPE”字段已被定义为关键字。但上面的查询不会返回任何内容。如果将“TYPE”值从“AIRPORT”更改为“airport”（小写），我会得到结果。我做错了什么？

注意＃我的努力是让这个查询工作，所以我可以利用过滤器缓存（节点查询缓存）。

提前致谢！

更新 - 1：添加GET索引/ _mapping

Answer 1

以下是解决这个问题的方法：

DELETE index
PUT index
{
  "mappings": {
    "default": {
      "properties": {
        "AIRPORT_CODE": {
          "type": "text"
        },
        "PROVINCE_NAME": {
          "type": "text"
        },
        "AIRPORT_NAME": {
          "type": "text"
        },
        "CITY_NAME": {
          "type": "text"
        },
        "TYPE": {
          "type": "keyword"
        },
        "COUNTRY_NAME": {
          "type": "text"
        }
      }
    }
  }
}
PUT index/default/1
{
  "AIRPORT_CODE": "SQA",
  "PROVINCE_NAME": "California",
  "AIRPORT_NAME": "Santa Ynez Airport",
  "CITY_NAME": "SANTA YNEZ",
  "TYPE": "AIRPORT"
}
PUT index/default/2
{
  "PROVINCE_NAME": "SANTIAGO",
  "CITY_NAME": "SANTIAGO",
  "COUNTRY_NAME": "DOMINICAN REPUBLIC",
  "TYPE": "HOTEL"
}
GET index/_search
{
    "query": {
        "bool": {
            "filter": [
                {
                    "term": {
                        "TYPE": "AIRPORT"
                    }
                }
            ]
        }
    }
}

为什么我的术语查询不起作用？
