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