• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach ca vien gioi bon hong minh ) OR ( te sach che vien gioi he thong (tin OR tinh) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach ca vien gioi bon hong minh ) or ( te sach che vien gioi he thong (tin OR tinh) ))~".
• Adding a wildcard symbol may retrieve word variants: (( tu sach ca vien gioi bon hong minh ) or ( te sach che vien gioi he thong (tin OR tinh) ))*.
