• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (te sach)) ky tang ma hoa. hieu van ((cam duc) OR (cam xuc)) van thanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ky tang ma hoa. hieu van ((cam duc) OR (cam xuc)) van thanh vai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) ky tang ma hoa. hieu van ((cam duc) OR (cam xuc)) van thanh vai cuu tre*".
