• If you are trying to use Boolean operators, they must be ALL CAPS: (((("graph bradley john ray") OR ("graph bradley john r"))) OR ("raja r von roy")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"graph bradley john ray\") OR (\"graph bradley john r\"))) or (\"raja r von roy\"))".
• Removing quotes may allow a broader search: (((( graph bradley john ray ) OR ( graph bradley john r ))) or ( raja r von roy )).
• Adding a wildcard symbol may retrieve word variants: (((("graph bradley john ray") OR ("graph bradley john r"))) or ("raja r von roy"))*.
