• If you are trying to use Boolean operators, they must be ALL CAPS: (( (phung OR phong) thi qua san. van dung he mo ) OR ( nhung bai quen vang. noi dung hoci co )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( (phung OR phong) thi qua san. van dung he mo ) or ( nhung bai quen vang. noi dung hoci co ))".
