• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu manh) OR (hieu nganh)) - thanh truong dao thuong ((cong dan) OR (huong dan)) toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu manh) or (hieu nganh)) - thanh truong dao thuong ((cong dan) OR (huong dan)) toan cao".
• Adding a wildcard symbol may retrieve word variants: doc ((hieu manh) or (hieu nganh)) - thanh truong dao thuong ((cong dan) OR (huong dan)) toan cao*.
