• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((thien anh) OR (chieu sang)) - thanh trung ((ha dung) OR (hai dung)) cong dan toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((thien anh) or (chieu sang)) - thanh trung ((ha dung) OR (hai dung)) cong dan toan ban*".
