• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((hieu manh) OR (((chieu sach) OR (chinh sach)))) - hanh tang cua tong cong tan tran cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((hieu manh) or (((chieu sach) OR (chinh sach)))) - hanh tang cua tong cong tan tran cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((hieu manh) or (((chieu sach) OR (chinh sach)))) - hanh tang cua tong cong tan tran cau*.
