• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ky sang) OR (ky nang)) ma hoa. hieu va cao suc va ((danh via) OR (danh gia)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ky sang) or (ky nang)) ma hoa. hieu va cao suc va ((danh via) OR (danh gia)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((ky sang) or (ky nang)) ma hoa. hieu va cao suc va ((danh via) OR (danh gia)) cua tre*.
