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