Perhaps you should try some spelling variations:
planning als » planning all, planning a, planning amp
turning back » turning talk, turning a, bring back
turning data » training data, learning data, turning a
yanling als » sampling als
wang yang » wang yan, wang liang, wang yanling
long sar » kong sar, long span, long arm

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 ((yanling als) OR (planning als)) benin ((turning back) OR (turning data)) long sar ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ((yanling als) or (planning als)) benin ((turning back) OR (turning data)) long sar ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang ((yanling als) or (planning als)) benin ((turning back) OR (turning data)) long sar ;*.
