• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y nang) OR (ly nang)) ((ma hoi) OR (xa hoi)). hieu viec cac xuc van hanh dao cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y nang) OR (ly nang)) ((ma hoi) or (xa hoi)). hieu viec cac xuc van hanh dao cua triet".
