• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((tu hang) OR (tu hung)) dai hoi. thien van cham so ban hanh lap ((cuu tre) OR (cua te))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((tu hang) OR (tu hung)) dai hoi. thien van cham so ban hanh lap ((cuu tre) or (cua te))~".
• Adding a wildcard symbol may retrieve word variants: tu sach ((tu hang) OR (tu hung)) dai hoi. thien van cham so ban hanh lap ((cuu tre) or (cua te))*.
