• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chu sang) OR (chu bang)) - thanh trung cua dung cong san ((thanh cau) OR (thanh mau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu sang) OR (chu bang)) - thanh trung cua dung cong san ((thanh cau) or (thanh mau))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu sang) OR (chu bang)) - thanh trung cua dung cong san ((thanh cau) or (thanh mau))*.
