• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu sach) OR (chieu sang)) - hanh tang cua khoang trong van ((thanh bac) OR (thanh bai))~.
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu sach) or (chieu sang)) - hanh tang cua khoang trong van ((thanh bac) or (thanh bai))*.
