Perhaps you should try some spelling variations:
"За советскии науку" » "За советская науку" (Expand Search), "За советскии наук" (Expand Search), "За советскии науки" (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 советские наука" » "За советское наука" (Expand Search), "За советская наука" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"За советскии науку\") OR (((\"За советскую наука\") OR (\"За советские наука\"))))~".
• Removing quotes may allow a broader search: (( За советскии науку ) OR ((( За советскую наука ) OR ( За советские наука ))))~.
• Adding a wildcard symbol may retrieve word variants: (("За советскии науку") OR ((("За советскую наука") OR ("За советские наука"))))*.
