• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu san) OR (tu ban)) ky sang lap hoa. ((hieu su) OR (tieu su)) chao xu va hanh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu san) or (tu ban)) ky sang lap hoa. ((hieu su) OR (tieu su)) chao xu va hanh vi cua te*".
