xuc va » duc va, tuc va, luc va
tai va » thai va, mai va, tri va

• If you are trying to use Boolean operators, they must be ALL CAPS: so sach y ((((nang xa) OR (lang xa))) OR (nang x)) hoi. hieu ve cam xuc va van tai va thiet.
• Adding a wildcard symbol may retrieve word variants: so sach y ((((nang xa) or (lang xa))) or (nang x)) hoi. hieu ve cam xuc va van tai va thiet*.
