• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach v nang mai khoi. hieu ve cam quoc ban ((thanh va) OR (thanh ve)) ((cua duc) OR (luat tuc))~.
• Adding a wildcard symbol may retrieve word variants: tu sach v nang mai khoi. hieu ve cam quoc ban ((thanh va) or (thanh ve)) ((cua duc) or (luat tuc))*.
