• Performing a fuzzy search may retrieve terms with similar spellings: ((tu cach) or (te sach)) v nang o hoi. hieu ve cam xuc ((van anh) OR (van minh)) dai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cach) OR (te sach)) v nang o hoi. hieu ve cam xuc ((van anh) OR (van minh)) dai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cach) or (te sach)) v nang o hoi. hieu ve cam xuc ((van anh) OR (van minh)) dai cua te*".
