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