• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cach) OR (su sach)) ky nang tao khoi. ((hieu va) OR (lieu va)) cam duc va thanh tai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cach) or (su sach)) ky nang tao khoi. ((hieu va) OR (lieu va)) cam duc va thanh tai cua tre".
• Adding a wildcard symbol may retrieve word variants: ((tu cach) or (su sach)) ky nang tao khoi. ((hieu va) OR (lieu va)) cam duc va thanh tai cua tre*.
