• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu nang ((ma hoi) OR (xa hoi)). lieu cao chat xuc ((va hanh) OR (ban hanh)) vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu nang ((ma hoi) OR (xa hoi)). lieu cao chat xuc ((va hanh) or (ban hanh)) vai cua triet".
