• Performing a fuzzy search may retrieve terms with similar spellings: (("advanced functions in complexity program") OR ("using in python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced functions in complexity program\") OR (\"using in python python programming\"))*".
• Removing quotes may allow a broader search: (( advanced functions in complexity program ) OR ( using in python python programming ))*.
