• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (toc sach)) thu lang xa hoi. hieu van ((cam duc) OR (cam xuc)) tan hanh tai chau tho~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (toc sach)) thu lang xa hoi. hieu van ((cam duc) OR (cam xuc)) tan hanh tai chau tho*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (toc sach)) thu lang xa hoi. hieu van ((cam duc) OR (cam xuc)) tan hanh tai chau tho*".
