• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chinh sach) OR (chieu sang)) - manh tung cap hang nong ((dan than) OR (van than)) cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chinh sach) or (chieu sang)) - manh tung cap hang nong ((dan than) OR (van than)) cap".
