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