• If you are trying to use Boolean operators, they must be ALL CAPS: ho hieu lang - thanh thanh ((cua trung) OR (xuan trung)) cong tan ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho hieu lang - thanh thanh ((cua trung) OR (xuan trung)) cong tan ((toan cau) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: ho hieu lang - thanh thanh ((cua trung) OR (xuan trung)) cong tan ((toan cau) or (toan tap))*.
