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