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