• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ty nang ((cao hoa) OR (cao khoa)). lieu va cam xuc va dinh ((biet cua) OR (viet ha)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ty nang ((cao hoa) OR (cao khoa)). lieu va cam xuc va dinh ((biet cua) or (viet ha)) te*".
