• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su sach)) ky ((tang ma) OR (mang may)) hoi. hieu ve cam xuc ban thanh phan cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) or (su sach)) ky ((tang ma) OR (mang may)) hoi. hieu ve cam xuc ban thanh phan cua tre".
• Adding a wildcard symbol may retrieve word variants: ((su sac) or (su sach)) ky ((tang ma) OR (mang may)) hoi. hieu ve cam xuc ban thanh phan cua tre*.
