• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((te sach) OR (toc sach)) minh ((do gia) OR (ho gia)) tuong ) OR ((((( tu sach hinh mai giao cong ) OR ( thu sach kinh bmai giaoi cong ))) OR ( tu sach ((kinh hmai) OR (kinh hai)) giao cong )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((te sach) or (toc sach)) minh ((do gia) OR (ho gia)) tuong ) or ((((( tu sach hinh mai giao cong ) or ( thu sach kinh bmai giaoi cong ))) or ( tu sach ((kinh hmai) or (kinh hai)) giao cong ))))".
