• Performing a fuzzy search may retrieve terms with similar spellings: (( chuong trinh han ban va cac su co ((nuoi viet) OR (nguoi viet)) nam ) or ( chuong tinh chat dan ca cac ty ((co cuoi) or (co nguoi)) viet nam ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( chuong trinh han ban va cac su co ((nuoi viet) OR (nguoi viet)) nam ) OR ( chuong tinh chat dan ca cac ty ((co cuoi) OR (co nguoi)) viet nam )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( chuong trinh han ban va cac su co ((nuoi viet) OR (nguoi viet)) nam ) or ( chuong tinh chat dan ca cac ty ((co cuoi) or (co nguoi)) viet nam ))".
• Adding a wildcard symbol may retrieve word variants: (( chuong trinh han ban va cac su co ((nuoi viet) OR (nguoi viet)) nam ) or ( chuong tinh chat dan ca cac ty ((co cuoi) or (co nguoi)) viet nam ))*.
