• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu cach cha ke giao bon thong tin ) OR ( ((te sach) OR (toc sach)) nha ve gioi hoi trong tin ))~.
• Adding a wildcard symbol may retrieve word variants: (( tu cach cha ke giao bon thong tin ) or ( ((te sach) or (toc sach)) nha ve gioi hoi trong tin ))*.
