• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach dao ly gioi ((co thong) OR (co trong)) hinh ) OR ( te sach nha le giai don hong minh ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach dao ly gioi ((co thong) OR (co trong)) hinh ) or ( te sach nha le giai don hong minh ))~".
• Adding a wildcard symbol may retrieve word variants: (( tu sach dao ly gioi ((co thong) OR (co trong)) hinh ) or ( te sach nha le giai don hong minh ))*.
