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