• If you are trying to use Boolean operators, they must be ALL CAPS: te sach bai hang va hoi. hieu ((va cam) OR (va cao)) tuc ban ((thanh vi) OR (thanh ve)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach bai hang va hoi. hieu ((va cam) or (va cao)) tuc ban ((thanh vi) OR (thanh ve)) cua triet".
