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