• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien xanh) OR (((hien nhanh) OR (thien thanh)))) - anh tang cua nhung huong dan toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) or (((hien nhanh) OR (thien thanh)))) - anh tang cua nhung huong dan toan ban~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) or (((hien nhanh) OR (thien thanh)))) - anh tang cua nhung huong dan toan ban*.
