• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang xa hoi. hieu ((van cac) OR (van bac)) xuc va ((dinh dieu) OR (vinh dieu)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang xa hoi. hieu ((van cac) or (van bac)) xuc va ((dinh dieu) OR (vinh dieu)) cua te".
