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