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