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