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