• If you are trying to use Boolean operators, they must be ALL CAPS: co sac ((ky dong) OR (ky cong)) hoa hoi. ((hieu tu) OR (hien tu)) cam xuc van thanh van chia tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "co sac ((ky dong) OR (ky cong)) hoa hoi. ((hieu tu) or (hien tu)) cam xuc van thanh van chia tre".
