Perhaps you should try some spelling variations:
"За советскии науку" » "За советская науку" (Expand Search), "За советскии наук" (Expand Search), "За советскии науке" (Expand Search)
"За советские наука" » "За советское наука" (Expand Search), "За советская наука" (Expand Search)
"За советскую науки" » "За советская науки" (Expand Search), "За советское науки" (Expand Search), "За советском науки" (Expand Search), "За советскую наук" (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 советские наука\"))) OR (\"За советскую науки\"))~".
• Removing quotes may allow a broader search: (((( За советскии науку ) OR ( За советские наука ))) OR ( За советскую науки ))~.
• Adding a wildcard symbol may retrieve word variants: (((("За советскии науку") OR ("За советские наука"))) OR ("За советскую науки"))*.
