Perhaps you should try some spelling variations:
frisian john » frisian town, friedman john, brian john
des frisian » der frisian, west frisian
wang yang » wang yan, wang liang, wang yanling
wong star » lone star, wong sam
yang jie » yang jin, yang jui, yang xi
wong sau » wong sam, wong siu, wong shiu

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 jie) OR (yang di)) des frisian john ((wong star) OR (wong sau)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ((yang jie) or (yang di)) des frisian john ((wong star) OR (wong sau)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang ((yang jie) or (yang di)) des frisian john ((wong star) OR (wong sau)) ;*.
