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