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