• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu sach - ((hanh tranh) OR (hanh trinh)) cua dung phuong ban ((thanh hai) OR (thanh bac))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu sach - ((hanh tranh) OR (hanh trinh)) cua dung phuong ban ((thanh hai) or (thanh bac))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu sach - ((hanh tranh) OR (hanh trinh)) cua dung phuong ban ((thanh hai) or (thanh bac))*.
