• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((sang ma) OR (tang ma)) hoa. ((hieu va) OR (hieu qua)) cay qua ban thanh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((sang ma) or (tang ma)) hoa. ((hieu va) OR (hieu qua)) cay qua ban thanh vai cua tre*".
