• If you are trying to use Boolean operators, they must be ALL CAPS: (((("nato science theories 1.3:, mathematical and physical sciences") OR ("nato science three 1.3:, mathematical and physical sciences"))) OR ("national science theories 3:, mathematical and physical sciences")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"nato science theories 1.3:, mathematical and physical sciences\") OR (\"nato science three 1.3:, mathematical and physical sciences\"))) or (\"national science theories 3:, mathematical and physical sciences\"))".
• Removing quotes may allow a broader search: (((( nato science theories 1.3:, mathematical and physical sciences ) OR ( nato science three 1.3:, mathematical and physical sciences ))) or ( national science theories 3:, mathematical and physical sciences )).
• Adding a wildcard symbol may retrieve word variants: (((("nato science theories 1.3:, mathematical and physical sciences") OR ("nato science three 1.3:, mathematical and physical sciences"))) or ("national science theories 3:, mathematical and physical sciences"))*.
