Perhaps you should try some spelling variations:
"За советское науку" » "За советское науки" (Expand Search), "За советское наука" (Expand Search), "За советское науке" (Expand Search)
"За советская науку" » "За советская науки" (Expand Search), "За советская наука" (Expand Search), "За советская науке" (Expand Search)
"За советские наук" » "За советскии наук" (Expand Search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("За советское науку") OR ("За советская науку"))) OR ("За советские наук"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"За советское науку\") OR (\"За советская науку\"))) OR (\"За советские наук\"))*".
• Removing quotes may allow a broader search: (((( За советское науку ) OR ( За советская науку ))) OR ( За советские наук ))*.
