truong cua » truong ca, truong quan, truong cao
nhung dong » nhung don, nhung cong, nhung dung

• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu tinh) OR (chieu sang)) - manh ((trung cua) OR (truong cua)) nhung dong doanh van ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) or (chieu sang)) - manh ((trung cua) OR (truong cua)) nhung dong doanh van ban~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) or (chieu sang)) - manh ((trung cua) OR (truong cua)) nhung dong doanh van ban*.
