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