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