• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach han vien gian trong thanh tien ) OR ( su sach cha de gian cong khong tin ))~.
• Adding a wildcard symbol may retrieve word variants: (( te sach han vien gian trong thanh tien ) or ( su sach cha de gian cong khong tin ))*.
