• If you are trying to use Boolean operators, they must be ALL CAPS: chao ((chu xanh) OR (chu manh)) - thanh ban cua nhung cong vang ((toan cao) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chao ((chu xanh) OR (chu manh)) - thanh ban cua nhung cong vang ((toan cao) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: chao ((chu xanh) OR (chu manh)) - thanh ban cua nhung cong vang ((toan cao) or (toan ban))*.
