What products and version are you using: InfluxDB 1.8
Where did you look before opening the issue: At the bottom of the above page where it says "Please, open an issue."
The examples are supposed to limit "results to series in the shard group that contain a timestamp in the last minute" or to return "all series in shard groups that contain a timestamp in the last 28 days", but, respectively, the clauses WHERE time < now() - 1m and WHERE time < now() - 28d are backwards. They could be changed to WHERE now() - 1m < time and WHERE now() - 28d < time.
