• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (vu sach)) ty ((hang xa) OR (hang ca)) hoi. hieu ve phan thuc day danh vu cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (vu sach)) ty ((hang xa) OR (hang ca)) hoi. hieu ve phan thuc day danh vu cua te~".
• Adding a wildcard symbol may retrieve word variants: ((te sach) or (vu sach)) ty ((hang xa) OR (hang ca)) hoi. hieu ve phan thuc day danh vu cua te*.
