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