• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y lang xa hoi. hieu ((va cham) OR (tu cham)) luc ((va doanh) OR (van doanh)) cap cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y lang xa hoi. hieu ((va cham) or (tu cham)) luc ((va doanh) OR (van doanh)) cap cua te*".
