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