• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) OR (chieu sang)) - hoang manh cua nhung ((cong san) or (cong tan)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) OR (chieu sang)) - hoang manh cua nhung ((cong san) or (cong tan)) toan ban*.
