• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu tang - ((hanh trang) OR (thanh trung)) cua nhan tong ((vang toan) OR (dang toan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu tang - ((hanh trang) or (thanh trung)) cua nhan tong ((vang toan) OR (dang toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: doi chieu tang - ((hanh trang) or (thanh trung)) cua nhan tong ((vang toan) OR (dang toan)) cau*.
