• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - ((anh tang) OR (hanh trang)) ca thuong cong vinh ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - ((anh tang) or (hanh trang)) ca thuong cong vinh ((toan cau) OR (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - ((anh tang) or (hanh trang)) ca thuong cong vinh ((toan cau) OR (toan cao))*.
