• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ky nang xa hoi. lieu va choi xu ((va dinh) OR (va kinh)) ca cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) ky nang xa hoi. lieu va choi xu ((va dinh) OR (va kinh)) ca cua tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (te sach)) ky nang xa hoi. lieu va choi xu ((va dinh) OR (va kinh)) ca cua tre*.
