• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ty nang x hoi. hieu van tham xuc va ((danh va) OR (doanh va)) cau tren*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) ty nang x hoi. hieu van tham xuc va ((danh va) OR (doanh va)) cau tren*".
