• If you are trying to use Boolean operators, they must be ALL CAPS: (("graph bradley john roy") OR ((("raja r von roy") OR ("raja 2 von roy")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"graph bradley john roy\") or (((\"raja r von roy\") OR (\"raja 2 von roy\"))))".
• Removing quotes may allow a broader search: (( graph bradley john roy ) or ((( raja r von roy ) OR ( raja 2 von roy )))).
• Adding a wildcard symbol may retrieve word variants: (("graph bradley john roy") or ((("raja r von roy") OR ("raja 2 von roy"))))*.
