• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu xanh) OR (chieu xanh)) - ((hanh trang) OR (hanh trinh)) cua thuong thong van hang va~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) OR (chieu xanh)) - ((hanh trang) or (hanh trinh)) cua thuong thong van hang va~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) OR (chieu xanh)) - ((hanh trang) or (hanh trinh)) cua thuong thong van hang va*.
