• If you are trying to use Boolean operators, they must be ALL CAPS: (( su sach ((nha ve) OR (nhan ve)) gioi bo thong minh ) OR ( so sach bua ke giai tao thong minh ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su sach ((nha ve) OR (nhan ve)) gioi bo thong minh ) or ( so sach bua ke giai tao thong minh ))~".
• Adding a wildcard symbol may retrieve word variants: (( su sach ((nha ve) OR (nhan ve)) gioi bo thong minh ) or ( so sach bua ke giai tao thong minh ))*.
