• Performing a fuzzy search may retrieve terms with similar spellings: (("advanced duplication in computer program") OR ("by computational code computing program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced duplication in computer program\") OR (\"by computational code computing program\"))*".
• Removing quotes may allow a broader search: (( advanced duplication in computer program ) OR ( by computational code computing program ))*.
