• If you are trying to use Boolean operators, they must be ALL CAPS: (( te ((sach danh) OR (sach tranh)) di ((gia tuong) OR (gia thanh)) ) OR ((( tu sach minh di gia cong ) OR ((( tu ((sach hinh) OR (((sach han) OR (sach dao)))) bai giang tuong ) OR ( tu sach ((sinh dai) OR (si dai)) giaoi tuong ))))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te ((sach danh) or (sach tranh)) di ((gia tuong) or (gia thanh)) ) or ((( tu sach minh di gia cong ) or ((( tu ((sach hinh) or (((sach han) OR (sach dao)))) bai giang tuong ) or ( tu sach ((sinh dai) or (si dai)) giaoi tuong ))))))~".
• Adding a wildcard symbol may retrieve word variants: (( te ((sach danh) or (sach tranh)) di ((gia tuong) or (gia thanh)) ) or ((( tu sach minh di gia cong ) or ((( tu ((sach hinh) or (((sach han) OR (sach dao)))) bai giang tuong ) or ( tu sach ((sinh dai) or (si dai)) giaoi tuong ))))))*.
