• If you are trying to use Boolean operators, they must be ALL CAPS: (("tu mach hoc lam nguoi") OR ((("tu hach hoc lam nguoi") OR ("tu hoach hoa lam nguoi")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"tu mach hoc lam nguoi\") or (((\"tu hach hoc lam nguoi\") OR (\"tu hoach hoa lam nguoi\"))))".
