• Performing a fuzzy search may retrieve terms with similar spellings: (("advanced calculation in computer program") OR ("_ computational grid computing program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced calculation in computer program\") OR (\"_ computational grid computing program\"))".
• Removing quotes may allow a broader search: (( advanced calculation in computer program ) OR ( _ computational grid computing program )).
• Adding a wildcard symbol may retrieve word variants: (("advanced calculation in computer program") OR ("_ computational grid computing program"))*.
