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