• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach v nang ((me hoi) OR (ma hoa)). hieu va cac ((tuc va) OR (tuc xa)) danh cho cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach v nang ((me hoi) or (ma hoa)). hieu va cac ((tuc va) OR (tuc xa)) danh cho cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sach v nang ((me hoi) or (ma hoa)). hieu va cac ((tuc va) OR (tuc xa)) danh cho cua triet*.
