• Performing a fuzzy search may retrieve terms with similar spellings: (( te sach cha ((me gioi) OR (me nguoi)) con hong minh ) or ( te sach ha me giai bo cong thanh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach cha ((me gioi) OR (me nguoi)) con hong minh ) OR ( te sach ha me giai bo cong thanh ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach cha ((me gioi) OR (me nguoi)) con hong minh ) or ( te sach ha me giai bo cong thanh ))*".
