• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu sach - hanh trang da nang cong san ((than cua) OR (((thanh lap) OR (thanh hai))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu sach - hanh trang da nang cong san ((than cua) or (((thanh lap) OR (thanh hai))))~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu sach - hanh trang da nang cong san ((than cua) or (((thanh lap) OR (thanh hai))))*.
