• Performing a fuzzy search may retrieve terms with similar spellings: (( ((te sach) or (toc sach)) minh dao gia tuong ) or ((((( tu sach hinh ((mai giao) or (mau giao)) cong ) or ( thu sach tinh bai giaoi cong ))) or ( tu sach ((((kinh hmai) OR (dinh hai))) or (kinh hai)) giao cong ))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((te sach) OR (toc sach)) minh dao gia tuong ) OR ((((( tu sach hinh ((mai giao) OR (mau giao)) cong ) OR ( thu sach tinh bai giaoi cong ))) OR ( tu sach ((((kinh hmai) OR (dinh hai))) OR (kinh hai)) giao cong )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((te sach) or (toc sach)) minh dao gia tuong ) or ((((( tu sach hinh ((mai giao) or (mau giao)) cong ) or ( thu sach tinh bai giaoi cong ))) or ( tu sach ((((kinh hmai) OR (dinh hai))) or (kinh hai)) giao cong ))))".
• Adding a wildcard symbol may retrieve word variants: (( ((te sach) or (toc sach)) minh dao gia tuong ) or ((((( tu sach hinh ((mai giao) or (mau giao)) cong ) or ( thu sach tinh bai giaoi cong ))) or ( tu sach ((((kinh hmai) OR (dinh hai))) or (kinh hai)) giao cong ))))*.
