• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (vu khach)) ky nang xa hoi. hieu ke chau phu la hanh vi ((va triet) OR (ve triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) OR (vu khach)) ky nang xa hoi. hieu ke chau phu la hanh vi ((va triet) or (ve triet))".
