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