• If you are trying to use Boolean operators, they must be ALL CAPS: doc hieu xanh - manh trung ((tam hang) OR (((tam thuong) OR (tai thuong)))) huong dan thanh cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc hieu xanh - manh trung ((tam hang) or (((tam thuong) OR (tai thuong)))) huong dan thanh cau~".
• Adding a wildcard symbol may retrieve word variants: doc hieu xanh - manh trung ((tam hang) or (((tam thuong) OR (tai thuong)))) huong dan thanh cau*.
