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