• If you are trying to use Boolean operators, they must be ALL CAPS: doc hieu sach - thanh trang ((va dung) OR (vat dung)) ((cong quang) OR (cong vang)) toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc hieu sach - thanh trang ((va dung) OR (vat dung)) ((cong quang) or (cong vang)) toan cao".
