• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang cao hoi. ((((hiem he) OR (hiem xe))) OR (hieu le)) nam tu va danh sai su triet.
• Adding a wildcard symbol may retrieve word variants: tu sach y nang cao hoi. ((((hiem he) or (hiem xe))) or (hieu le)) nam tu va danh sai su triet*.
