• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach ((ca ve) OR (ca va)) gioi hoan hoang minh ) OR ( su sach ha te moi thong thuong tin ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach ((ca ve) OR (ca va)) gioi hoan hoang minh ) or ( su sach ha te moi thong thuong tin ))~".
• Adding a wildcard symbol may retrieve word variants: (( thu sach ((ca ve) OR (ca va)) gioi hoan hoang minh ) or ( su sach ha te moi thong thuong tin ))*.
