Perhaps you should try some spelling variations:
klang iii » klang die
zwang iii » zugang iii
best data » test data, cost data, best damn
wong shiu » cong shu, song shin, wong sau
wang you » want you, wang yong, chang you
data kie » data ki, data kit, data kate
wong siu » kong siu, wong sau, wong siew

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: wang you ((klang iii) OR (zwang iii)) best data kie ((wong shiu) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang you ((klang iii) OR (zwang iii)) best data kie ((wong shiu) or (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang you ((klang iii) OR (zwang iii)) best data kie ((wong shiu) or (wong siu)) ;*.
