• If you are trying to use Boolean operators, they must be ALL CAPS: (( learning-based a simulation techniques ) OR ( learning-based tool implantation technique )).
• Adding a wildcard symbol may retrieve word variants: (( learning-based a simulation techniques ) or ( learning-based tool implantation technique ))*.
