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