• If you are trying to use Boolean operators, they must be ALL CAPS: (("thu sach hoi dap nguoi") OR ((("phuong cach hoc dai nguoi") OR ("phuong anh hoc dai nguoi")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"thu sach hoi dap nguoi\") or (((\"phuong cach hoc dai nguoi\") OR (\"phuong anh hoc dai nguoi\"))))".
