• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ly nang) OR (ky nang)) xa hoi. hieu ve cam tuc xa nhan ((loai ca) OR (loai cay)) tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ly nang) or (ky nang)) xa hoi. hieu ve cam tuc xa nhan ((loai ca) OR (loai cay)) tren".
• Adding a wildcard symbol may retrieve word variants: tu sach ((ly nang) or (ky nang)) xa hoi. hieu ve cam tuc xa nhan ((loai ca) OR (loai cay)) tren*.
