• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach ((cha te) OR (cua te)) cao cong thong minh ) OR ( vu khach cha me giai con khong minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach ((cha te) OR (cua te)) cao cong thong minh ) or ( vu khach cha me giai con khong minh ))".
• Adding a wildcard symbol may retrieve word variants: (( tu sach ((cha te) OR (cua te)) cao cong thong minh ) or ( vu khach cha me giai con khong minh ))*.
