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