• The words AND, OR and NOT may confuse the search; try adding quotes: "chao ((chu xanh) OR (chu manh)) - anh mang cua nhung cong ((trinh toan) or (tinh toan)) ban~".
• Adding a wildcard symbol may retrieve word variants: chao ((chu xanh) OR (chu manh)) - anh mang cua nhung cong ((trinh toan) or (tinh toan)) ban*.
