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