• If you are trying to use Boolean operators, they must be ALL CAPS: su sach v nang xa hoi. hieu ((ve cam) OR (va cam)) luc va hang cua ((cua triet) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach v nang xa hoi. hieu ((ve cam) or (va cam)) luc va hang cua ((cua triet) OR (cua viet))".
