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