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