Perhaps you should try some spelling variations:
"radio science stories 1:, physics" » "radio science studies 1:, physics", "radio science theories 1:, physics", "radio science stories 14:, physics", "radio science stories 12:, physics", "radio 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 3:, physics"
"radio science series 1:, physics" » "radio science services 1:, physics", "radio science theories 1:, physics", "radio sciences serious 1:, physics", "radio science series 3:, physics"
"radio science series 2:, physics" » "radio science services 2:, physics", "radio science theories 2:, physics", "radio sciences serious 2:, physics", "radio science series 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 ((((("radio science series 1:, physics") OR ("radio science stories 1:, physics"))) OR ("radio science series 2:, physics")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"nato science series 1:, physics\") or (((((\"radio science series 1:, physics\") OR (\"radio science stories 1:, physics\"))) or (\"radio science series 2:, physics\"))))".
• Removing quotes may allow a broader search: (( nato science series 1:, physics ) or ((((( radio science series 1:, physics ) OR ( radio science stories 1:, physics ))) or ( radio science series 2:, physics )))).
• Adding a wildcard symbol may retrieve word variants: (("nato science series 1:, physics") or ((((("radio science series 1:, physics") OR ("radio science stories 1:, physics"))) or ("radio science series 2:, physics"))))*.
