• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((tu sach) OR (tu cach)) han li gioi dong thuong tin ) OR ( te sach ha me nguoi co thong tin ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((tu sach) OR (tu cach)) han li gioi dong thuong tin ) or ( te sach ha me nguoi co thong tin ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((tu sach) OR (tu cach)) han li gioi dong thuong tin ) or ( te sach ha me nguoi co thong tin ))*.
