What you type here filters the calendar you are looking at: the same view, with less in it. Plain words are ANDed, and each has to appear somewhere in the event: its title, where it is, its notes, or the people on it. Wrap a phrase in "double quotes" to match it exactly.

Press Enter and the same query becomes a search across every calendar, including the ones you have switched off. Hiding a calendar is about the drawing, never about the data.

Filters

These narrow without searching text, so they work on their own as well as beside words. Mixing them is an AND.

cal:name	Only that calendar. Matches part of the name; cal:fam is enough.
with:who	Someone on it: an attendee or the organiser, by name or address.
in:where	The location field.
is:span	The long ones: anything covering more than a day. This is the whole rail.
is:allday / is:timed	All-day events, or the ones with a clock on them.
is:recurring	Anything that repeats.
is:free / is:busy	Whether it claims the time or is only a note in it (iCalendar's TRANSP).
is:cancelled	Called off, but still on the calendar.

Regex

Tick Regex and the words become POSIX regular expressions, matched case-insensitively by Postgres itself against an indexed column, so standup|jour fixe or ^Q[1-4] costs about what a word costs. rx: in front of a term turns it on for that query without reaching for the tickbox.
