• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - hanh ((tran van) OR (luan van)) nhung cong san ((thanh lap) OR (thanh ca)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hanh ((tran van) OR (luan van)) nhung cong san ((thanh lap) or (thanh ca))".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - hanh ((tran van) OR (luan van)) nhung cong san ((thanh lap) or (thanh ca))*.
