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