• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y lang ha hoi. hieu van cau ((((xuc va) OR (duc va))) OR (thuc va)) thanh di cuu tre.
• Adding a wildcard symbol may retrieve word variants: su sach y lang ha hoi. hieu van cau ((((xuc va) or (duc va))) or (thuc va)) thanh di cuu tre*.
