• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach y xang van hoa. ((hieu ve) OR (hieu va)) ((cam duc) OR (cao duc)) ban thanh va cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach y xang van hoa. ((hieu ve) or (hieu va)) ((cam duc) OR (cao duc)) ban thanh va cua te".
