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