范围查询
执行数值范围查询
对数字字段的范围查询返回介于给定起始值和结束值之间的值：
FT.SEARCH index "@field:[start end]"
你也可以使用FILTER参数，但你需要知道查询执行计划是不同的，因为过滤器是在查询字符串（例如*）被评估后应用的：
FT.SEARCH index "*" FILTER field start end
开始和结束值
开始和结束值默认是包含的，但你可以在值前加上(来将其从范围中排除。
值 -inf、inf 和 +inf 是有效值，允许您定义开放范围。
结果集
开放范围查询可能导致结果集过大。
默认情况下，FT.SEARCH 只返回前十个结果。LIMIT 参数帮助您滚动浏览结果集。SORTBY 参数确保结果集中的文档按指定顺序返回。
FT.SEARCH index "@field:[start end]" SORTBY field LIMIT page_start page_end
您可以在[FT.SEARCH命令参考](/commands/ft.search/)中找到关于使用LIMIT和SORTBY的更多详细信息。
示例
本节中的示例使用具有以下字段的模式：
| 字段名称 | 字段类型 |
|---|---|
price |
NUMERIC |
以下查询找到价格范围大于或等于500美元且小于或等于1000美元的自行车（500 <= price <= 1000）：
> FT.SEARCH idx:bicycle "@price:[500 1000]"
