Perhaps you should try some spelling variations:
"nato science stories 1:, physics" » "nato science studies 1:, physics", "nato science theories 1:, physics", "national science stories 1:, physics", "nato science stories 14:, physics", "nato science stories 12:, physics", "nato science stories 10:, physics"
"nato science series 1:, physics" » "nato science services 1:, physics", "nato science theories 1:, physics", "nato sciences serious 1:, physics", "national science series 1:, physics", "nato science series 2:, physics"
"radio science series 1:, physics" » "radio science services 1:, physics", "radio science theories 1:, physics", "radio sciences serious 1:, physics", "radio science series 2:, physics"
"radio science series 3:, physics" » "radio science services 3:, physics", "radio science theories 3:, physics", "radio sciences serious 3:, physics"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("nato science series 1:, physics") OR ("nato science stories 1:, physics"))) OR ((("radio science series 1:, physics") OR ("radio science series 3:, physics")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"nato science series 1:, physics\") OR (\"nato science stories 1:, physics\"))) or (((\"radio science series 1:, physics\") or (\"radio science series 3:, physics\"))))".
• Removing quotes may allow a broader search: (((( nato science series 1:, physics ) OR ( nato science stories 1:, physics ))) or ((( radio science series 1:, physics ) or ( radio science series 3:, physics )))).
• Adding a wildcard symbol may retrieve word variants: (((("nato science series 1:, physics") OR ("nato science stories 1:, physics"))) or ((("radio science series 1:, physics") or ("radio science series 3:, physics"))))*.
