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