I minimise them quite frequently these days for something I want to tuck away. A good way to surface them is the "App Exposé" feature (Preferences -> Trackpad -> More Gestures). Shows all the hidden windows for the current app.
It's different to Windows though. If they're looking for something more similar to Windows, maybe Command+H (hide the active app) is a better alternative.
