• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (chinh sach)) - thanh trung cua ((nhung huong) OR (nhung phuong)) dan toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (chinh sach)) - thanh trung cua ((nhung huong) OR (nhung phuong)) dan toan cao".
