• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"program complement\") OR (((\"program complemented\") OR (\"program complementinged\"))))*".
• Removing quotes may allow a broader search: (( program complement ) OR ((( program complemented ) OR ( program complementinged ))))*.
