• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (thuoc sach)) ((ly lang) OR (ly hang)) ha hoi. hieu va cao luc va thanh di cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) OR (thuoc sach)) ((ly lang) or (ly hang)) ha hoi. hieu va cao luc va thanh di cua te~".
• Adding a wildcard symbol may retrieve word variants: ((thu sach) OR (thuoc sach)) ((ly lang) or (ly hang)) ha hoi. hieu va cao luc va thanh di cua te*.
