Perhaps you should try some spelling variations:
david mant » david ian, david malone, david martin
wang yang » wang yan, wang liang, wang yanling
yang zili » yang dali, yang li
yang lin » yang jin, wang lin, yang li
david ma » david a, david m, david ian
form 2 » form _, form a, form i
haji » hadi

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 yang ((yang di) OR (((yang zili) OR (yang lin)))) form 2 ((david mant) OR (david ma)) haji ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ((yang di) or (((yang zili) or (yang lin)))) form 2 ((david mant) OR (david ma)) haji ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang ((yang di) or (((yang zili) or (yang lin)))) form 2 ((david mant) OR (david ma)) haji ;*.
