• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (vu khach)) v nang cao hoi. hieu van cau xuc va danh di ((cua triet) OR (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (vu khach)) v nang cao hoi. hieu van cau xuc va danh di ((cua triet) OR (cua viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (vu khach)) v nang cao hoi. hieu van cau xuc va danh di ((cua triet) OR (cua viet))*".
