• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - thanh tran tuan ((((thong cong) OR (tong cong))) OR (dung cong)) dan thanh lap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - thanh tran tuan ((((thong cong) OR (tong cong))) or (dung cong)) dan thanh lap*".
