本文介绍如何在特定索引和类型的映射中，通过修改字段属性启用Fielddate特性，实现对文本字段的快速聚合和排序操作，适用于Elasticsearch等搜索引擎优化场景。

这是要开启fielddate

可以执行
PUT /索引/_mapping/类型

{
  "properties": {
    "出问题的字段": {
      "type":     "text",
      "fielddata": true
    }
  }
}

在postman什么的执行的时候记得body得改为json，否则会失败

自动映射类型，数据类型自动映射为第一次收到数据时的类型，后续即使写数据时改变数据类型，但存储的还是第一次映射类型。第一次存储的数据类型为text，即使后续写入的数据类型为long，但写入数据库后还是text。字段类型为text，不支持直接用字段名查询，应该用字段名.keyword；
