• If you are trying to use Boolean operators, they must be ALL CAPS: nato ((((science stories) OR (science services))) OR (science theories)) b:, physics.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nato ((((science stories) OR (science services))) or (science theories)) b:, physics".
• Adding a wildcard symbol may retrieve word variants: nato ((((science stories) OR (science services))) or (science theories)) b:, physics*.
