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