• If you are trying to use Boolean operators, they must be ALL CAPS: vu bach van tang ma hoi. ((hieu va) OR (hieu ve)) cam vuc van thanh vi ((su tien) OR (tu tieng))~.
• Adding a wildcard symbol may retrieve word variants: vu bach van tang ma hoi. ((hieu va) or (hieu ve)) cam vuc van thanh vi ((su tien) or (tu tieng))*.
