You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"program complement\") OR (((\"program implementinged\") OR (\"program implemented\"))))~".
• Removing quotes may allow a broader search: (( program complement ) OR ((( program implementinged ) OR ( program implemented ))))~.
• Adding a wildcard symbol may retrieve word variants: (("program complement") OR ((("program implementinged") OR ("program implemented"))))*.
