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