• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach tu sang ma hoa. hieu va cam ((xuc va) OR (duc va)) hanh ((tai cau) OR (tai cao)) treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach tu sang ma hoa. hieu va cam ((xuc va) or (duc va)) hanh ((tai cau) OR (tai cao)) treo".
