Perhaps you should try some spelling variations:
"nato science three b:, physics" » "nato science thin b:, physics", "nato science third b:, physics", "national science three b:, physics", "nato science three big:, physics", "nato science three 11:, physics"
"nato science theories b:, physics" » "national science theories b:, physics", "nato science theories 3:, physics", "nato science theories 4:, physics", "nato science theories 1:, 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 theories b:, physics") OR ("nato science three b:, physics"))) OR ("radio science theories b:, physics"))) OR ("nato science theory b:, physics"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"nato science theories b:, physics\") OR (\"nato science three b:, physics\"))) or (\"radio science theories b:, physics\"))) or (\"nato science theory b:, physics\"))*".
• Removing quotes may allow a broader search: (((((( nato science theories b:, physics ) OR ( nato science three b:, physics ))) or ( radio science theories b:, physics ))) or ( nato science theory b:, physics ))*.
