• Performing a fuzzy search may retrieve terms with similar spellings: (( tu cach ta me gioi con thong tin ) or ( thuoc sach ((ha me) OR (cha me)) gioi cong khong tinh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu cach ta me gioi con thong tin ) OR ( thuoc sach ((ha me) OR (cha me)) gioi cong khong tinh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu cach ta me gioi con thong tin ) or ( thuoc sach ((ha me) OR (cha me)) gioi cong khong tinh ))".
