• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu tang van hoa. hieu van cham luc van ((dinh te) OR (kinh te)) ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu tang van hoa. hieu van cham luc van ((dinh te) OR (kinh te)) ((cua tre) or (cuu tre))*".
