• Performing a fuzzy search may retrieve terms with similar spellings: (( ((tu sach) OR (tu cach)) cha me giai con duong minh ) or ( su sach cha me gioi con khong minh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((tu sach) OR (tu cach)) cha me giai con duong minh ) OR ( su sach cha me gioi con khong minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((tu sach) OR (tu cach)) cha me giai con duong minh ) or ( su sach cha me gioi con khong minh ))".
• Adding a wildcard symbol may retrieve word variants: (( ((tu sach) OR (tu cach)) cha me giai con duong minh ) or ( su sach cha me gioi con khong minh ))*.
