• If you are trying to use Boolean operators, they must be ALL CAPS: (( bo sac cua ((ke giai) OR (ke giao)) can hong minh ) OR ( su sach han me gioi bon thong hinh ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( bo sac cua ((ke giai) OR (ke giao)) can hong minh ) or ( su sach han me gioi bon thong hinh ))~".
• Adding a wildcard symbol may retrieve word variants: (( bo sac cua ((ke giai) OR (ke giao)) can hong minh ) or ( su sach han me gioi bon thong hinh ))*.
