• If you are trying to use Boolean operators, they must be ALL CAPS: cho chu xang - ((hanh tang) OR (((hanh mang) OR (nhanh mang)))) chua bang cong san toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho chu xang - ((hanh tang) or (((hanh mang) OR (nhanh mang)))) chua bang cong san toan cau~".
• Adding a wildcard symbol may retrieve word variants: cho chu xang - ((hanh tang) or (((hanh mang) OR (nhanh mang)))) chua bang cong san toan cau*.
