• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) lo hang cau hoi. hieu qua cam xuc va danh ((vi cua) OR (di cua)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) OR (toc sach)) lo hang cau hoi. hieu qua cam xuc va danh ((vi cua) or (di cua)) triet*".
