• Performing a fuzzy search may retrieve terms with similar spellings: (( thu sach che ve gian con dong tin ) or ( tu sach ha me ((nguoi ban) OR (nguoi ba)) phong tin ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach che ve gian con dong tin ) OR ( tu sach ha me ((nguoi ban) OR (nguoi ba)) phong tin )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach che ve gian con dong tin ) or ( tu sach ha me ((nguoi ban) OR (nguoi ba)) phong tin ))".
• Adding a wildcard symbol may retrieve word variants: (( thu sach che ve gian con dong tin ) or ( tu sach ha me ((nguoi ban) OR (nguoi ba)) phong tin ))*.
