repeating events drown out others in edit

I'm trying to find and edit an event from 2016 that is choking vdirsyncer but when I try to search for it, my searches all get drowned out by repeating events. The event text is "NB move Oliver's car" -- when I search for "Oliver" I get infinite instances of the yearly event, "Oliver's birthday"; if I search for "NB" I get a couple events that don't (to my knowledge) include "NB" at all, but they're all weekly repeating events with no end set, so they just keep coming up and the search is clearly moving forward (not back) in time.

There doesn't seem to be a way to search by date. It seems like there should be a way to narrow my edit search. Either I want to edit an older (or future) instance of the event, or the event I'm looking for isn't part of this repeating series.

So this is a feature request: I'd like a way to narrow my search in khal edit.

(The HTML is also annoying but that's gcal and 🤷‍♀️ )

Start at the khal edit command and reproduce the reported khal edit NB search, focusing on how recurring events are expanded and presented. Define and test a way to narrow results to a requested date or historical/future instance, with completion shown by finding and editing the intended event without recurring results drowning it out.
