• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly hang co hoi. hieu qua ca tuc ((va thanh) OR (gia thanh)) ((di su) OR (da su)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly hang co hoi. hieu qua ca tuc ((va thanh) or (gia thanh)) ((di su) OR (da su)) triet*".
