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

Try widening your search to All Fields.

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 10:, physics") OR ((("nato science series 2:, physics") OR ("nato science series 3:, physics"))))) OR ((("radio science series 10:, physics") OR ("radio science stories 10:, physics")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"nato science series 10:, physics\") or (((\"nato science series 2:, physics\") OR (\"nato science series 3:, physics\"))))) or (((\"radio science series 10:, physics\") or (\"radio science stories 10:, physics\"))))".
• Removing quotes may allow a broader search: (((( nato science series 10:, physics ) or ((( nato science series 2:, physics ) OR ( nato science series 3:, physics ))))) or ((( radio science series 10:, physics ) or ( radio science stories 10:, physics )))).
• Adding a wildcard symbol may retrieve word variants: (((("nato science series 10:, physics") or ((("nato science series 2:, physics") OR ("nato science series 3:, physics"))))) or ((("radio science series 10:, physics") or ("radio science stories 10:, physics"))))*.
