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