• Performing a fuzzy search may retrieve terms with similar spellings: (("variance function and coding program") OR ("advanced and coding using program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"variance function and coding program\") OR (\"advanced and coding using program\"))".
• Removing quotes may allow a broader search: (( variance function and coding program ) OR ( advanced and coding using program )).
• Adding a wildcard symbol may retrieve word variants: (("variance function and coding program") OR ("advanced and coding using program"))*.
