• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky nang x hoi. hieu qua cam xuc ((va thanh) OR (((ban thanh) OR (ban hanh)))) sinh cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky nang x hoi. hieu qua cam xuc ((va thanh) or (((ban thanh) OR (ban hanh)))) sinh cua tre".
• Adding a wildcard symbol may retrieve word variants: vu sach ky nang x hoi. hieu qua cam xuc ((va thanh) or (((ban thanh) OR (ban hanh)))) sinh cua tre*.
