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