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