• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu tinh) OR (chieu sang)) - anh dung cua dung cong ((dan than) OR (van than)) cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) or (chieu sang)) - anh dung cua dung cong ((dan than) OR (van than)) cap".
