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