Look for Hungarian private torrent trackers.

Set the language in Radarr/Sonarr and wait.

And use culture-specific trackers. Most trackers, especially public ones, tend to be mostly English, Japanese for anime, and some major non-english films (e.g. Parasite).

in my case for spanish i search adding to the title ESP (for español) but its a lot harder and usually with only leechers. English its a lot easier sadly. But sometimes i got lucky and then i seed whatever i found, so i would say search 'Title HUN'

I always add the year if the name is common

I would include the 2-letter and 3-letter code in your searches

That seems to be kinda standard. If Sonarr/Radarr have a more elegant solution than looking in the title, that might be preferred
