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