Mistake: "Using 'buscar' when you mean an official search."
Correction: Use 'registrar' when a policeman or official is searching/inspecting bags or property.

⭐ Usage Tips
Serious tone
This meaning of 'registrar' is more invasive than 'buscar.' Use it when someone is formally looking through something to find evidence or hidden items.
