• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) tu ((nano bac) OR (dan ba)) hoi. hieu qua cac xuc qua kinh tri cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (so sach)) tu ((nano bac) or (dan ba)) hoi. hieu qua cac xuc qua kinh tri cua te".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (so sach)) tu ((nano bac) or (dan ba)) hoi. hieu qua cac xuc qua kinh tri cua te*.
