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