• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang ((lai hoi) OR (dai hoi)). hieu ve cham ((xuc ban) OR (duc ban)) hanh de cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang ((lai hoi) OR (dai hoi)). hieu ve cham ((xuc ban) or (duc ban)) hanh de cua te*".
