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