• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (chieu tinh)) - thanh trung ((phap chong) OR (pham hong)) cong san than cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (chieu tinh)) - thanh trung ((phap chong) OR (pham hong)) cong san than cau*".
