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