• Performing a fuzzy search may retrieve terms with similar spellings: (( tu sach ((xa le) OR (xa la)) nguoi cong thong minh ) or ( tu cach pha me gioi dong thong minh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach ((xa le) OR (xa la)) nguoi cong thong minh ) OR ( tu cach pha me gioi dong thong minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach ((xa le) OR (xa la)) nguoi cong thong minh ) or ( tu cach pha me gioi dong thong minh ))".
• Adding a wildcard symbol may retrieve word variants: (( tu sach ((xa le) OR (xa la)) nguoi cong thong minh ) or ( tu cach pha me gioi dong thong minh ))*.
