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