• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien xanh - thanh truong quan nhung ((tuong dan) OR (xuong dan)) ((thanh chau) OR (khan cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - thanh truong quan nhung ((tuong dan) OR (xuong dan)) ((thanh chau) or (khan cap))~".
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - thanh truong quan nhung ((tuong dan) OR (xuong dan)) ((thanh chau) or (khan cap))*.
