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