• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang liang) OR (wang ryan)) wang hua chen song jin ((wong sau) OR (wong sam)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang liang) or (wang ryan)) wang hua chen song jin ((wong sau) OR (wong sam)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang liang) or (wang ryan)) wang hua chen song jin ((wong sau) OR (wong sam)) ;*.
