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