• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ((ky sang) OR (((ky tang) OR (kho tang)))) lap hoi. hieu su chao xu ban thanh vi cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ((ky sang) or (((ky tang) OR (kho tang)))) lap hoi. hieu su chao xu ban thanh vi cua te~".
• Adding a wildcard symbol may retrieve word variants: tu sai ((ky sang) or (((ky tang) OR (kho tang)))) lap hoi. hieu su chao xu ban thanh vi cua te*.
