• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ty hang) OR (thi hong)) co hoc. hieu ve cham ((xuc va) OR (duc va)) hanh vai cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ty hang) or (thi hong)) co hoc. hieu ve cham ((xuc va) OR (duc va)) hanh vai cau treo".
• Adding a wildcard symbol may retrieve word variants: su sach ((ty hang) or (thi hong)) co hoc. hieu ve cham ((xuc va) OR (duc va)) hanh vai cau treo*.
