Searching for flight between 2 cities, don't know the airline

[Vienna42]

Question from a Newbie:
I am looking for a flight from Sweden (possibly Stockholm) to Budapest on the afternoon of December 11th 2019. I don't know the airline. I didn't have any luck searching for it via the history search (I have a subscription) - did I do something wrong in the search or can't you search for flights like that?

The problem is, it's not a normal, scheduled flight, but a one time charter flight. I still haven't found a way to search for those flights a few days after they took place. Maybe because the history flight search is limited to scheduled flights.
