• If you are trying to use Boolean operators, they must be ALL CAPS: (( (phung OR phong) thi quan va. thoi quen suc lap ) OR ( nhung hai quan van. thoi chuyen tu lap )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( (phung OR phong) thi quan va. thoi quen suc lap ) or ( nhung hai quan van. thoi chuyen tu lap ))".
• Adding a wildcard symbol may retrieve word variants: (( (phung OR phong) thi quan va. thoi quen suc lap ) or ( nhung hai quan van. thoi chuyen tu lap ))*.
