• If you are trying to use Boolean operators, they must be ALL CAPS: ((doan tran) OR (hoan tran)) thanh - hanh trinh thi nhung cong dan ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doan tran) OR (hoan tran)) thanh - hanh trinh thi nhung cong dan ((toan cau) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: ((doan tran) OR (hoan tran)) thanh - hanh trinh thi nhung cong dan ((toan cau) or (toan tap))*.
