• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (te sach)) ty nang x hoi. hieu ((van tham) OR (van chat)) xuc va danh va cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ty nang x hoi. hieu ((van tham) OR (van chat)) xuc va danh va cau tren*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) ty nang x hoi. hieu ((van tham) OR (van chat)) xuc va danh va cau tren*".
