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