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