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