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