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