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