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