• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((dinh trong) OR (sinh trong)) quang ((dung huong) OR (dung thuong)) dan thanh mau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((dinh trong) OR (sinh trong)) quang ((dung huong) or (dung thuong)) dan thanh mau".
