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

• Performing a fuzzy search may retrieve terms with similar spellings: (("covariance function and closing program") OR ("advanced distribution coding decoding program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"covariance function and closing program\") OR (\"advanced distribution coding decoding program\"))*".
• Removing quotes may allow a broader search: (( covariance function and closing program ) OR ( advanced distribution coding decoding program ))*.
