• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu ((sach bai) OR (sach xa)) me gioi con thong minh ) OR ( tu sach ba me nguoi con song hinh ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu ((sach bai) OR (sach xa)) me gioi con thong minh ) or ( tu sach ba me nguoi con song hinh ))~".
• Adding a wildcard symbol may retrieve word variants: (( tu ((sach bai) OR (sach xa)) me gioi con thong minh ) or ( tu sach ba me nguoi con song hinh ))*.
