• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach cha ((me giai) OR (ve giai)) co trong tin ) OR ( so sach che te giao hang thuong tin ))~.
• Adding a wildcard symbol may retrieve word variants: (( tu sach cha ((me giai) or (ve giai)) co trong tin ) or ( so sach che te giao hang thuong tin ))*.
