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