• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty lang ((van hoi) OR (van hoe)). hieu van nam ((xuc ban) OR (duc manh)) danh hai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty lang ((van hoi) OR (van hoe)). hieu van nam ((xuc ban) or (duc manh)) danh hai cua triet".
