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