• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ly nang ma hoa. ((hieu ve) OR (hieu va)) cham xuc ((van anh) OR (tran anh)) dai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ly nang ma hoa. ((hieu ve) OR (hieu va)) cham xuc ((van anh) or (tran anh)) dai cua tre*".
