Perhaps you should try some spelling variations:
"За советская науку" » "За советская наук" (Expand Search), "За советская наука" (Expand Search), "За советская науке" (Expand Search)
"За советскую науки" » "За советскии науки" (Expand Search), "За советское науки" (Expand Search), "За советском науки" (Expand Search)
"За советские науки" » "За советскии науки" (Expand Search), "За советское 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 советская науку\") OR (((\"За советскую науки\") OR (\"За советские науки\"))))~".
• Removing quotes may allow a broader search: (( За советская науку ) OR ((( За советскую науки ) OR ( За советские науки ))))~.
• Adding a wildcard symbol may retrieve word variants: (("За советская науку") OR ((("За советскую науки") OR ("За советские науки"))))*.
