• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu cac nhanh va thuat hoa hoc ) OR ( thu sach ngon co huyet ((hoc hoc) OR (hoc hoi)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu cac nhanh va thuat hoa hoc ) or ( thu sach ngon co huyet ((hoc hoc) OR (hoc hoi)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( tu cac nhanh va thuat hoa hoc ) or ( thu sach ngon co huyet ((hoc hoc) OR (hoc hoi)) ))*.
