• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"nato basic services, series 10: applied sciences\") OR (\"nato basic services, series 10: applied science\"))) or (\"nato arw series, series 10: applied sciences\"))) or (\"nato iii series, series 1: applied sciences\"))".
• Removing quotes may allow a broader search: (((((( nato basic services, series 10: applied sciences ) OR ( nato basic services, series 10: applied science ))) or ( nato arw series, series 10: applied sciences ))) or ( nato iii series, series 1: applied sciences )).
• Adding a wildcard symbol may retrieve word variants: (((((("nato basic services, series 10: applied sciences") OR ("nato basic services, series 10: applied science"))) or ("nato arw series, series 10: applied sciences"))) or ("nato iii series, series 1: applied sciences"))*.
