Perhaps you should try some spelling variations:
liang using » liang ying, change using, liang liying
yang using » yang jing, making using, change using
test using » tests using, tested using, testing using
using bank » housing bank
loan sara » loan shark
loan data » loan rate
ai test » api test, i test, ii test

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 ((liang using) OR (yang using)) ai test using bank ((loan sara) OR (loan data)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((liang using) OR (yang using)) ai test using bank ((loan sara) or (loan data)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((liang using) OR (yang using)) ai test using bank ((loan sara) or (loan data)) ;*.
