• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) tao cao xa hoi. hieu qua cam xuc van anh ((va cuu) OR (va cau)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (vu sach)) tao cao xa hoi. hieu qua cam xuc van anh ((va cuu) OR (va cau)) tre".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (vu sach)) tao cao xa hoi. hieu qua cam xuc van anh ((va cuu) OR (va cau)) tre*.
