Perhaps you should try some spelling variations:
using bank » housing bank
test using » tests using, tested using, testing using
kong stara » kong sar
wang yong » wang yang, wang hyoung, wang yan
kong saur » kong sar, kong siu, kong your
yang xi » yang di, yang yi, yang jui
yang i » yang di, yang yi, yang li

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang yong ((yang i) OR (yang xi)) test using bank ((kong stara) or (kong saur)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yong ((yang i) OR (yang xi)) test using bank ((kong stara) OR (kong saur)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong ((yang i) OR (yang xi)) test using bank ((kong stara) or (kong saur)) ;".
• Adding a wildcard symbol may retrieve word variants: wang yong ((yang i) OR (yang xi)) test using bank ((kong stara) or (kong saur)) ;*.
