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