• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (thu sach)) ky lang xa hoi. lieu va cao xuc van hanh ((vi cua) OR (di cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (thu sach)) ky lang xa hoi. lieu va cao xuc van hanh ((vi cua) OR (di cua)) triet".
