• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang oanh) OR (wang yang)) tran hua irene yang jie ((song sam) OR (kong sar)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang oanh) OR (wang yang)) tran hua irene yang jie ((song sam) or (kong sar)) ;".
• Adding a wildcard symbol may retrieve word variants: ((wang oanh) OR (wang yang)) tran hua irene yang jie ((song sam) or (kong sar)) ;*.
