• If you are trying to use Boolean operators, they must be ALL CAPS: tu tang ky lang van hoc. hieu va ((tham duc) OR (tham du)) va thanh hai ((cau thi) OR (cau trieu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu tang ky lang van hoc. hieu va ((tham duc) OR (tham du)) va thanh hai ((cau thi) or (cau trieu))".
