The Settings menu has a Search: Use Specific Place Names (airports, landmarks) option, on by default. When it is on, searches can return specific named places — an airport, a university, a park — with locality context added. When it is off, searches return city-level (locality-only) results instead. Turn it off if you prefer to always add the surrounding city rather than a specific point.
