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