• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach y lang xa hoi. hieu ve cac luc va ((thanh loi) OR (thanh de)) ((cua tu) OR (cua cu))~.
• Adding a wildcard symbol may retrieve word variants: vu sach y lang xa hoi. hieu ve cac luc va ((thanh loi) or (thanh de)) ((cua tu) or (cua cu))*.
