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