I'm looking to be able to get a list off all emails by a certain date, no matter where they are in Thunderbird. I feel like this should be pretty simple, but:
only return emails whose contents have the date, or part of the date, in them.
I tried to use this add-on:
but it doesn't have a global search, it only lets you search the mail in your current view.
No other addons I could find via Thunderbird's Addon search looked useful.
