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