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