Perhaps you should try some spelling variations:
"За советское науку" » "За советское наук" (Expand Search), "За советское науке" (Expand Search)
"За советскую наука" » "За советская наука" (Expand Search), "За советскии наука" (Expand Search), "За советские наука" (Expand Search)
"За советскую науки" » "За советская науки" (Expand Search), "За советскии науки" (Expand Search), "За советские науки" (Expand Search), "За советскую наук" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("За советское науку") OR ("За советскую наука"))) OR ("За советскую науки"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"За советское науку\") OR (\"За советскую наука\"))) OR (\"За советскую науки\"))*".
• Removing quotes may allow a broader search: (((( За советское науку ) OR ( За советскую наука ))) OR ( За советскую науки ))*.
