• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu sang) OR (chieu sach)) - thanh trung cua vuong hoang van ((thanh cac) OR (thanh ca))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu sang) or (chieu sach)) - thanh trung cua vuong hoang van ((thanh cac) OR (thanh ca))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu sang) or (chieu sach)) - thanh trung cua vuong hoang van ((thanh cac) OR (thanh ca))*.
