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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"За советское науку\") OR (((\"За советскую науки\") OR (\"За советскии науки\"))))~".
• Removing quotes may allow a broader search: (( За советское науку ) OR ((( За советскую науки ) OR ( За советскии науки ))))~.
• Adding a wildcard symbol may retrieve word variants: (("За советское науку") OR ((("За советскую науки") OR ("За советскии науки"))))*.
