in OS (version 3.0. onwards)
- Tap first the location field at the top of the screen
- write any city/location from the country in question to get a search list of all events near that city in near future
- tap "reverse pyramid" for advanced filters
- activate Country filter and click "Close"
in Android, we are still working on the advanced search so you can currently (in version 1.0) only search events nearby to any specific city, but not filter them to a specific country.
