• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computation and feeding programs\") OR (\"computing computer and computer programming\"))~".
• Removing quotes may allow a broader search: (( using computation and feeding programs ) OR ( computing computer and computer programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computation and feeding programs") OR ("computing computer and computer programming"))*.
