• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (doi chieu)) xanh - canh manh cua ((nhung cong) OR (thong cong)) dan toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (doi chieu)) xanh - canh manh cua ((nhung cong) OR (thong cong)) dan toan ban*.
