• Performing a fuzzy search may retrieve terms with similar spellings: (( tu sach nha ke nguoi ((co hong) OR (co hoang)) minh ) or ( thu sach cha ve gioi dan dong minh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach nha ke nguoi ((co hong) OR (co hoang)) minh ) OR ( thu sach cha ve gioi dan dong minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach nha ke nguoi ((co hong) OR (co hoang)) minh ) or ( thu sach cha ve gioi dan dong minh ))".
• Adding a wildcard symbol may retrieve word variants: (( tu sach nha ke nguoi ((co hong) OR (co hoang)) minh ) or ( thu sach cha ve gioi dan dong minh ))*.
