• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach cua ((me gioi) OR (me giai)) cam hong hinh ) OR ( tu sach tac de giai san thong minh ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach cua ((me gioi) OR (me giai)) cam hong hinh ) or ( tu sach tac de giai san thong minh ))~".
• Adding a wildcard symbol may retrieve word variants: (( tu sach cua ((me gioi) OR (me giai)) cam hong hinh ) or ( tu sach tac de giai san thong minh ))*.
