• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sach - thanh trung ((dap nhung) OR (((voi nhung) OR (thi nhung)))) huong dan than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - thanh trung ((dap nhung) or (((voi nhung) OR (thi nhung)))) huong dan than cap~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - thanh trung ((dap nhung) or (((voi nhung) OR (thi nhung)))) huong dan than cap*.
