• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (((so sach) OR (bo sach)))) y nang xa hoi. hieu ve cam thu dac hanh doi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (((so sach) OR (bo sach)))) y nang xa hoi. hieu ve cam thu dac hanh doi cua tre".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (((so sach) OR (bo sach)))) y nang xa hoi. hieu ve cam thu dac hanh doi cua tre*.
