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