• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc tien) OR (hoc vien)) manh - nhanh sinh cua khong ((cong san) OR (huong dan)) thanh ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc tien) OR (hoc vien)) manh - nhanh sinh cua khong ((cong san) or (huong dan)) thanh ban".
