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