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