• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) ((ty hang) OR (thi hang)) va hoi. hieu qua cam dua ban hanh via cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sach)) ((ty hang) OR (thi hang)) va hoi. hieu qua cam dua ban hanh via cua te~".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (so sach)) ((ty hang) OR (thi hang)) va hoi. hieu qua cam dua ban hanh via cua te*.
