• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sach ly) OR (sach y)) vang ma hoi. hieu qua chat tuc ((xa thanh) OR (ta thanh)) lai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sach ly) OR (sach y)) vang ma hoi. hieu qua chat tuc ((xa thanh) or (ta thanh)) lai cua triet".
