Perhaps you should try some spelling variations:
"radio science series b:, physics" » "radio science services b:, physics", "radio science stories b:, physics", "radio science theories b:, physics", "radio science series 1:, physics", "radio science series 10:, physics"
"radio science series 12:, physics" » "radio science services 12:, physics", "radio science stories 12:, physics", "radio science theories 12:, physics", "radio science series 2:, physics", "radio science series 1:, physics", "radio science series 10:, physics"
"radio science series 11:, physics" » "radio science services 11:, physics", "radio science stories 11:, physics", "radio science theories 11:, physics", "radio science series 1:, physics", "radio science series 10:, physics", "radio science series 3:, 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: (((("radio science series b:, physics") OR ("radio science series 12:, physics"))) OR ("radio science series 11:, physics")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"radio science series b:, physics\") OR (\"radio science series 12:, physics\"))) or (\"radio science series 11:, physics\"))".
• Removing quotes may allow a broader search: (((( radio science series b:, physics ) OR ( radio science series 12:, physics ))) or ( radio science series 11:, physics )).
• Adding a wildcard symbol may retrieve word variants: (((("radio science series b:, physics") OR ("radio science series 12:, physics"))) or ("radio science series 11:, physics"))*.
