• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sach) OR (so sanh)) ty xang xa hoi. hieu va cam xuc ((va minh) OR (vua minh)) hoa cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) OR (so sanh)) ty xang xa hoi. hieu va cam xuc ((va minh) or (vua minh)) hoa cua viet".
• Adding a wildcard symbol may retrieve word variants: ((so sach) OR (so sanh)) ty xang xa hoi. hieu va cam xuc ((va minh) or (vua minh)) hoa cua viet*.
