date filter operator "is set"
Posted on behalf of Ricardo Signes. Original posting date 2019-02-08.
I can find unscheduled events by searching for "earliest_start never"
It's not clear that there's a great way to search for scheduled events. I'd like an is_set operator for date fields, the inverse of never.
In the meantime, I'll probably use "earlier_start after (yesterday)" unless there's a better option.
