• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ((ma hoi) OR (mai hoi)). lieu va nam ((tuc va) OR (thuc dan)) hanh vi cuu tre.
• Adding a wildcard symbol may retrieve word variants: te sach y nang ((ma hoi) or (mai hoi)). lieu va nam ((tuc va) or (thuc dan)) hanh vi cuu tre*.
