• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) ky lang van hoi. hieu ve ((coc tuc) OR (coc luc)) va tinh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sach)) ky lang van hoi. hieu ve ((coc tuc) OR (coc luc)) va tinh vi cua te".
