• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach v nang ma hoa. hieu ((va lam) OR (va lap)) ((tuc va) OR (thuc va)) thanh di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach v nang ma hoa. hieu ((va lam) OR (va lap)) ((tuc va) or (thuc va)) thanh di cua te".
