• If you are trying to use Boolean operators, they must be ALL CAPS: (( so sach cha va ((nguoi con) OR (nguoi co)) hoang minh ) OR ( su sach xa ke giai bo thong minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( so sach cha va ((nguoi con) OR (nguoi co)) hoang minh ) or ( su sach xa ke giai bo thong minh ))".
