范围过滤器不适用于 "gt" 运算符但适用于 "lt"

Question

我正在使用弹性搜索为我的文档编制索引，并希望根据特定属性过滤文档。这是我的代码：

filter.push({
            range: {"audience.ethnicity.asian" : { gt: 50 } }
        })

它不适用于 gt 运算符（发回不一致的结果）但适用于 lt 运算符

filter.push({
                range: {"audience.ethnicity.asian" : { lt: 50 } }
            })

这效果令人惊讶。我仔细检查了属性值是一个整数。我尝试了很多不同的方法，但似乎无法弄清楚我错过了什么。映射：

  "audience": {
    "properties": {
      "age": {
        "properties": {

Answer 1

在您的映射中，audience.ethnicity.asian 字段是文本类型，因此范围查询进行的是 词汇范围比较 而不是 数值范围比较.

在数值上，123 > 50，但在词汇上，123 < 50，因为 ASCII 字符 1 在 5 之前，这正是您遇到的问题。

我不确定您是否可以使用 audience.ethnicity.Asian 字段，它是一个浮点数。如果不是，您需要将 audience.ethnicity.asian 的映射更改为数字类型（integer、float 等）并重新索引您的数据。

范围过滤器不适用于 "gt" 运算符但适用于 "lt"
