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