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