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