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