Perhaps you should try some spelling variations:
thinking john » thinking can, thinking form, thinking home
thinking four » thinking form, thinking about, thinking aloud
ngosong shin » song shin
yang liang » wang liang, yan liang, peng liang
yang yang » wang yang, wang yan
als case » als care, goals case, sales case

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 liang) OR (yang yang)) als case ((thinking john) OR (thinking four)) ngosong shin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang liang) or (yang yang)) als case ((thinking john) OR (thinking four)) ngosong shin ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang liang) or (yang yang)) als case ((thinking john) OR (thinking four)) ngosong shin ;*.
