• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ((ky mang) OR (ke mang)) ((lai hoi) OR (lai hoa)). hieu duoc chao xu va hanh vai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ((ky mang) OR (ke mang)) ((lai hoi) or (lai hoa)). hieu duoc chao xu va hanh vai cua te~".
• Adding a wildcard symbol may retrieve word variants: tu sac ((ky mang) OR (ke mang)) ((lai hoi) or (lai hoa)). hieu duoc chao xu va hanh vai cua te*.
