• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (vu bach)) thu ang xa hoi. lieu va cac duc va minh va ((cua viet) OR (hoa viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) OR (vu bach)) thu ang xa hoi. lieu va cac duc va minh va ((cua viet) or (hoa viet))".
