• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using concentration in coding program\") OR (\"using combinational java computer programming\"))~".
• Removing quotes may allow a broader search: (( using concentration in coding program ) OR ( using combinational java computer programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using concentration in coding program") OR ("using combinational java computer programming"))*.
