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