 - The window width of the aggregation period is specified by the keyword INTERVAL, with the shortest interval being 10 milliseconds (10a); it also supports an offset (the offset must be less than the interval), which is the offset of the time window division compared to "UTC moment 0". The SLIDING statement is used to specify the forward increment of the aggregation period, i.e., the duration of each window slide forward.
 - When using the INTERVAL statement, unless in very special cases, it is required to configure the timezone parameter in the taos.cfg configuration files of both the client and server to the same value to avoid frequent cross-time zone conversions by time processing functions, which can cause severe performance impacts.
 - The returned results have a strictly monotonically increasing time-series.
+- When using AUTO as the window offset, if the WHERE time condition is complex, such as multiple AND/OR/IN combinations, AUTO may not take effect. In such cases, you can manually specify the window offset to resolve the issue.
 - When using AUTO as the window offset, if the window width unit is d (day), n (month), w (week), y (year), such as: INTERVAL(1d, AUTO), INTERVAL(3w, AUTO), the TSMA optimization cannot take effect. If TSMA is manually created on the target table, the statement will report an error and exit; in this case, you can explicitly specify the Hint SKIP_TSMA or not use AUTO as the window offset.

 - 聚合时间段的窗口宽度由关键词 INTERVAL 指定，最短时间间隔 10 毫秒（10a）；并且支持偏移 offset（偏移必须小于间隔），也即时间窗口划分与“UTC 时刻 0”相比的偏移量。SLIDING 语句用于指定聚合时间段的前向增量，也即每次窗口向前滑动的时长。
 - 使用 INTERVAL 语句时，除非极特殊的情况，都要求把客户端和服务端的 taos.cfg 配置文件中的 timezone 参数配置为相同的取值，以避免时间处理函数频繁进行跨时区转换而导致的严重性能影响。
 - 返回的结果中时间序列严格单调递增。
+- 使用 AUTO 作为窗口偏移量时，如果 WHERE 时间条件比较复杂，比如多个 AND/OR/IN 互相组合，那么 AUTO 可能不生效，这种情况可以通过手动指定窗口偏移量进行解决。
 - 使用 AUTO 作为窗口偏移量时，如果窗口宽度的单位是 d (天), n (月), w (周), y (年)，比如: INTERVAL(1d, AUTO), INTERVAL(3w, AUTO)，此时 TSMA 优化无法生效。如果目标表上手动创建了TSMA，语句会报错退出；这种情况下，可以显式指定 Hint SKIP_TSMA 或者不使用 AUTO 作为窗口偏移量。
