Perhaps you should try some spelling variations:
tested using » test using, tests using, testing using
liang using » liang ying, yang using, change using
wang liang » wang yang
using bank » housing bank
loan shark » loan sharks, loan sharking
ai tested » _ tested, a nested, ai test
loan sara » loan data
using ai » using a, using big, using _

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

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