• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty sang ma hoa. ((hieu van) OR (lieu va)) cay qua ban thanh van ((cua tre) OR (cau treo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty sang ma hoa. ((hieu van) OR (lieu va)) cay qua ban thanh van ((cua tre) or (cau treo))*".
