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