Perhaps you should try some spelling variations:
"За советская науку" » "За советская наук" (Expand Search), "За советская науке" (Expand Search)
"За советские наука" » "За советскии наука" (Expand Search), "За советское наука" (Expand Search)
"За советскую науки" » "За советскии науки" (Expand Search), "За советское науки" (Expand Search), "За советском 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 советская науку") OR ("За советские наука"))) OR ("За советскую науки"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"За советская науку\") OR (\"За советские наука\"))) OR (\"За советскую науки\"))*".
• Removing quotes may allow a broader search: (((( За советская науку ) OR ( За советские наука ))) OR ( За советскую науки ))*.
