• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang xa hoi. lieu va cac luc va ((((thanh di) OR (thanh do))) OR (thanh de)) cua tre.
• Adding a wildcard symbol may retrieve word variants: su sach y nang xa hoi. lieu va cac luc va ((((thanh di) or (thanh do))) or (thanh de)) cua tre*.
