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