• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder on complexity posed problem\") OR (\"using coding python python programming\"))".
• Removing quotes may allow a broader search: (( coder on complexity posed problem ) OR ( using coding python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder on complexity posed problem") OR ("using coding python python programming"))*.
