So you want to search or want suggestions? A good tracker also has suggestions. You should never need to search on a search engine and it would also be slower.

There are local trackers everywhere, try to get an invite to them. I’m Hungarian, we have several invite only trackers for dubbed movies and other local content. Even they are invite only, it’s really easy to get an invite as a lot of folks have account on them.

For that kind of content I would look for your local communities on reddit, fb or whatever social media is common in your country. Try to find out what others use, and try to get an invite there.
